Tibetan Mysticism: Dream Yoga, Bardos and the Mystery of the Rainbow Body

Few spiritual traditions have attracted as much Western fascination as Tibetan Buddhism.

There are stories of monks maintaining awareness through dreams, meditators preparing consciously for death, reincarnated teachers being identified as children, elaborate mandalas representing transformed reality and advanced practitioners whose bodies are said to dissolve into light.

These ideas can sound like material from a fantasy novel. They also belong to living religious traditions with sophisticated philosophies and centuries of textual history.

The difficulty begins when everything is gathered together under the vague label “Tibetan mysticism” and presented as one secret system. Tibetan Buddhism contains several major schools, different lineages and enormous bodies of philosophy and ritual. Tibet also possesses the distinct Bön tradition, which developed in close interaction with Buddhism while maintaining its own identity.

There is no single Tibetan Mystery School and no one curriculum of hidden practices. What exists instead is something far more interesting: a religious culture that has spent centuries exploring whether the transitions in which we normally lose awareness, particularly sleep, dreaming and death, can become opportunities for awakening.

What do we mean by Tibetan mysticism?

The phrase is useful, but imprecise.

Most of the practices modern readers associate with Tibetan mysticism belong to Tibetan Buddhism, particularly its Vajrayana or tantric traditions. Buddhism entered Tibet from India over several centuries, becoming particularly influential from the seventh and eighth centuries onwards, and Tibetan scholars subsequently preserved enormous bodies of Indian Buddhist philosophy and tantric literature.

Over time, distinctly Tibetan systems of interpretation and practice developed.

The major Tibetan Buddhist traditions usually identified today include Nyingma, Kagyu, Sakya and Gelug, alongside other important lineages. Practices differ between and within them.

Dzogchen, for example, is particularly associated with Nyingma and Bön. The Six Yogas of Naropa became enormously influential within Kagyu traditions. Different systems approach death, dream, visualisation and meditation through their own lineages.

“Tibetan mysticism” is therefore best understood as an entrance into a large religious world rather than a claim that every Tibetan practitioner believes or practises exactly the same things.

Vajrayana: using experience as part of the path

Tibetan Buddhism belongs broadly within Mahayana Buddhism, with its emphasis on awakening for the benefit of all sentient beings.

Its Vajrayana traditions add tantric practices involving mantra, visualisation, ritual, subtle-body systems, mandalas and identification with enlightened forms.

The underlying logic can sound surprising to outsiders. Instead of treating ordinary experience only as something to escape, tantric systems can use the very mechanisms through which ordinary identity is constructed as material for transformation.

Visualisation becomes practice. The body becomes practice. Emotion can become practice. Dreaming can become practice. Eventually even dying can become practice.

This does not mean every experience is automatically spiritually useful. It means that within a particular philosophical and ritual framework, states normally dominated by confusion can become opportunities to recognise how mind constructs experience.

Why the teacher matters

The teacher-student relationship in Vajrayana is sometimes described in modern spiritual language as a direct transfer of spiritual energy.

Traditional Vajrayana frames the relationship more precisely.

Many tantric practices require empowerment or initiation from a qualified teacher, together with textual transmission and practical instruction. The empowerment establishes permission and context for a particular practice and places the student within a lineage through which those teachings have been transmitted.

Historical objects demonstrate this directly. Tibetan initiation cards, for example, could be arranged into mandalas while a teacher guided a disciple through visualisation and initiation into a particular Vajrayana deity practice.

The relationship can certainly be understood by practitioners in devotional and spiritual terms, but it is more than an exchange of invisible energy.

The teacher transmits a practice, a lineage and an interpretation of what the practice is for.

Why some teachings are restricted

Western esotericism sometimes interprets tantric secrecy as proof that extraordinarily powerful techniques were being hidden from ordinary people.

The traditional rationale is more complex.

Advanced practices sit inside philosophical and ethical frameworks. Their imagery can be deliberately challenging or easy to misunderstand when removed from that context.

Empowerment can also create commitments. A practitioner is not simply acquiring a technique but entering a relationship with a teacher, a lineage and a particular spiritual discipline.

Restricted transmission therefore does not automatically imply a hidden supernatural technology. It can also reflect the belief that certain practices only make sense after the foundations necessary to understand them have been established.

Dream yoga: becoming conscious inside the dream

Of all Tibetan practices, dream yoga is perhaps the easiest for modern readers to recognise.

At its simplest, dream yoga involves becoming aware that one is dreaming while the dream continues.

That sounds very similar to lucid dreaming.

The difference is purpose.

Modern lucid dreaming is often practised for curiosity, creativity, problem-solving or simply the pleasure of controlling dreams. Tibetan dream yoga uses lucidity within a much larger Buddhist project.

The dream becomes a laboratory for examining the nature of experience.

Dreams and the problem of apparent reality

A dream can feel completely convincing while it is happening.

There are people, places, danger, desire and a temporary identity. Sometimes there are even memories explaining how you arrived there.

Only when lucidity appears do you recognise that the environment you have been responding to as externally solid is being generated under very different conditions.

That makes dreaming extraordinarily useful to Buddhist philosophy.

Buddhist texts used dreams as metaphors for impermanence and insubstantiality long before formal Tibetan dream-yoga systems developed. Dream yoga makes the metaphor experiential.

Instead of merely being told that phenomena are dreamlike, the practitioner discovers what it feels like to recognise apparent solidity while still inside the experience.

Dream yoga is not simply about controlling dreams

The first achievement is usually lucidity, but that is not the final objective.

Practices can involve deliberately changing dream appearances, confronting fear, recognising the dream's lack of fixed external reality and attempting to maintain increasing stability of awareness.

The point is partly to weaken the automatic conviction that appearances possess the solidity we ordinarily give them.

If a terrifying dream figure can be transformed once its nature is recognised, what does that teach about the emotional reactions produced by waking appearances?

The waking world is not therefore being declared a literal dream.

The training concerns the mind's relationship with appearance.

Different lineages have different dream-yoga traditions

Dream yoga is found within more than one Tibetan Buddhist tradition.

It forms part of the Six Yogas of Naropa, a system particularly important within Kagyu Buddhism. Nyingma and Dzogchen traditions also developed important teachings around dreams, sleep and clear-light awareness.

The phrase “Tibetan dream yoga” therefore contains several centuries of development and interpretation.

There is no single practice manual representing every lineage.

Sleep as spiritual territory

Dream yoga belongs to a larger ambition: maintaining awareness during states in which ordinary consciousness usually disappears.

Every day, consciousness passes through waking, dreaming and deep sleep.

Most of us experience those boundaries as gaps. We remember lying down, perhaps remember dreams, and then wake.

Advanced Tibetan practices ask whether awareness can become increasingly continuous across those transitions.

This has obvious implications for meditation.

It also has an even more important implication.

Sleep becomes practice for death.

Why dreaming and dying are connected

Tibetan Buddhist systems frequently compare the processes of sleep with the processes of death.

Both involve the dissolution of an ordinary waking relationship with body, environment and identity.

Dream yoga therefore does more than provide additional time for meditation. It trains the practitioner to recognise experience during a transition when familiar structures become unstable.

That becomes crucial within Tibetan teachings about the bardos.

If recognition can occur during dreaming, perhaps recognition can also occur during dying and whatever follows it.

What is a bardo?

The Tibetan term bardo means an intermediate or transitional state.

In Western popular culture it has become almost synonymous with the period between death and rebirth.

That is only part of its meaning.

Tibetan systems can describe several bardos, including ordinary life, meditation, dreaming, dying, the luminous reality encountered around death and the process leading towards rebirth.

This creates a powerful idea.

We are not only in transition when we die.

Life itself is a bardo. Dreaming is a bardo. Meditation is a bardo.

Human existence is structured by thresholds.

Death is simply the threshold we fear most.

The Tibetan Book of the Dead

No discussion of Tibetan approaches to death can avoid the famous Tibetan Book of the Dead.

The title itself, however, is Western.

There is no single Tibetan book universally known by that name.

The work popularised in English under that title comes from a particular collection of Nyingma funerary teachings usually associated with the Bardo Thödol, often translated as Liberation Through Hearing in the Intermediate State.

The texts form part of a larger Tibetan tradition and are traditionally attributed to Padmasambhava and later revelation by the treasure revealer Karma Lingpa.

The collection became enormously influential in the West after its twentieth-century translation and publication under the title The Tibetan Book of the Dead.

Its modern reputation has sometimes detached it from its ritual and doctrinal setting and transformed it into a universal handbook of consciousness after death.

The original context is much more specific.

What happens in the bardo?

According to the traditions associated with these texts, death is not simply instantaneous extinction followed immediately by another birth.

There are transitional experiences in which ordinary identity and perception dissolve.

The practitioner may encounter luminosity, peaceful and wrathful forms, powerful visions and ultimately tendencies drawing consciousness towards another rebirth.

One central teaching is that these appearances are not simply external monsters or gods threatening the deceased.

Recognition matters.

If appearances can be recognised in relation to the nature of mind rather than reacted to through fear and attachment, liberation may be possible.

The mythology is elaborate.

The psychological insight beneath it is striking: human beings suffer partly because they fail to recognise what their own minds are doing.

Are the bardos scientifically proven states after death?

No.

Tibetan Buddhist traditions describe them as realities within a religious worldview involving karma, rebirth and liberation.

Modern neuroscience has not demonstrated the Tibetan bardo system as an empirical map of post-mortem consciousness.

Near-death experiences, meditation research and studies of consciousness raise fascinating questions about subjective experience around death. They do not prove the detailed geography of Tibetan after-death teachings.

That distinction does not make the bardo concept irrelevant.

Even as a contemplative framework, it asks a profound question: how prepared are we for the moment when everything we use to define ourselves starts disappearing?

Phowa: the transference of consciousness

Another Tibetan practice directly concerned with death is phowa.

The term is generally translated as transference or transfer of consciousness.

Within Tibetan Buddhist tantric traditions, phowa involves preparing to direct consciousness at the moment of death towards liberation or a favourable rebirth, often within a pure realm associated with a Buddha such as Amitabha.

Phowa appears in several Tibetan lineages and is especially well known within systems connected to the Six Yogas of Naropa.

It is therefore a genuine traditional practice rather than a modern invention.

Phowa as an advanced lineage practice

Phowa is traditionally taught within a lineage rather than approached simply as a general mindfulness exercise.

Its methods belong to a larger Buddhist framework involving rebirth, pure lands, tantric initiation and preparation for death.

There are much simpler Buddhist contemplations of impermanence and mortality that do not require advanced tantric instruction.

Phowa is interesting because it demonstrates how seriously Tibetan Buddhism treats the process of dying.

Spiritual practice is not concerned only with how a person lives.

It can also prepare for how consciousness meets dissolution.

Why death is not considered spiritual failure

Modern wellness culture can become strangely uncomfortable with mortality.

Spirituality is often sold through ideas of healing, abundance, optimisation and extending vitality.

Tibetan traditions take a different route.

Human beings die. The people we love die. Everything currently possessed will eventually separate from us.

This is not presented merely as a negative thought.

Impermanence is one of the basic conditions that makes awakening urgent.

Remembering death can clarify what matters because it exposes how much energy is spent defending things that cannot ultimately remain fixed.

The more extraordinary practices around death sit on top of this very sober foundation.

Mandalas: not just sacred geometry

Another Tibetan practice frequently simplified in modern spirituality is the mandala.

A Tibetan mandala is sometimes described merely as sacred geometry or as a visual pattern designed to raise consciousness through universal proportions.

Historically, it is much richer.

In Vajrayana Buddhism, a mandala can represent the cosmic abode of an enlightened deity, often visualised as a palace with a central figure surrounded by an ordered retinue.

It can be painted, constructed from coloured sand, represented through sculpture or generated entirely within visualisation.

The mandala is a map, but not simply a map of physical space.

It maps transformed reality.

Entering the mandala

During tantric initiation and meditation, a practitioner may imagine entering the mandala, encountering its central deity and eventually identifying with enlightened qualities represented by that form.

The architecture of the mandala organises consciousness symbolically.

Outer space and inner transformation reflect one another.

This is why describing mandalas simply as geometric patterns for meditation misses much of their meaning.

The geometry serves a religious system.

A mandala contains deities, directions, elements, states of mind and transformed forms of perception.

It is closer to an entire symbolic universe compressed into one image.

Sand mandalas and impermanence

The famous Tibetan practice of creating intricate mandalas from coloured sand has become one of the most recognisable symbols of Buddhism in the West.

Their destruction after completion is frequently interpreted as a lesson in impermanence.

That interpretation fits Buddhist teaching, although each mandala also belongs to a specific ritual tradition rather than functioning merely as generic mindfulness art.

Hours or days of meticulous construction can culminate in dismantling the image.

For modern spectators, the act can feel almost shocking.

Why destroy something so beautiful?

Buddhism returns the question.

Why assume beauty becomes more valuable if it can be kept?

Deity yoga and transforming identity

One of the most misunderstood Vajrayana practices involves visualising oneself as an enlightened deity or Buddha-form.

From outside, this can look like worshipping supernatural beings or pretending to become a god.

The philosophical mechanism is subtler.

Ordinary identity is already constructed through memory, body image, habits, expectations and conceptual labels.

Tantric visualisation deliberately interrupts that construction.

Instead of rehearsing the familiar identity, the practitioner generates an enlightened form and environment according to a detailed contemplative system.

The purpose is not to inflate the ego into divine status.

It is to undermine the assumption that the ego's current version of identity is fixed.

Is deity yoga a form of manifestation?

Not in the modern sense.

Deity yoga is not primarily about imagining a desired car, relationship or career until physical reality produces it.

Its goal is Buddhist awakening.

The visualisation trains perception within a framework involving emptiness, compassion, wisdom and liberation from cyclic existence.

There can be interesting comparisons with modern ideas about mental rehearsal and constructed identity.

But tantric visualisation belongs to a very different spiritual project from contemporary manifestation practice.

Tulkus: can a teacher return?

Perhaps no Tibetan institution seems stranger to outsiders than the tulku system.

A tulku is a teacher recognised within Tibetan Buddhist tradition as the reincarnation or intentional rebirth of a previous religious master.

After the death of an important lama, disciples may search for a child believed to continue that teacher's incarnation lineage.

The most internationally famous example is the Dalai Lama institution, though many tulku lineages exist.

The system developed historically over centuries and became deeply connected with Tibetan religious institutions.

For believers it demonstrates the continuity of consciousness and compassionate return.

For historians it is also a distinctive system through which religious authority, education and lineage were maintained.

How are tulkus recognised?

Popular accounts focus heavily on children identifying objects belonging to a previous lama.

Such tests do occur in some recognition narratives.

But the wider process can involve predictions, dreams, divination, instructions left by previous teachers, the location and circumstances of a child's birth and assessment by senior religious figures.

Practices vary between lineages.

Recognition is therefore not one standard paranormal experiment repeated under laboratory conditions.

It takes place inside a religious institution whose participants already accept rebirth as part of the Buddhist worldview.

That does not settle the metaphysical question either way.

It tells us what kind of evidence the tradition itself considers meaningful.

Does the tulku system prove reincarnation?

Not scientifically.

Stories of children apparently remembering previous lives are fascinating, in Tibet and elsewhere, and researchers have attempted to investigate some reincarnation claims.

But the institutional recognition of a tulku is not equivalent to controlled scientific proof that one person's consciousness has transferred into another body.

For Tibetan Buddhists, the system operates inside a much larger understanding of karma and rebirth.

The stories can remain intriguing without being asked to prove more than the available evidence allows.

Dzogchen: the Great Perfection

Some of the most extraordinary claims associated with Tibet emerge from Dzogchen, usually translated as the Great Perfection.

Dzogchen is especially associated with the Nyingma school of Tibetan Buddhism and with Bön, though its history and textual traditions are complex.

At the centre is the possibility of directly recognising the fundamental nature of mind or awareness.

This should not be simplified into “realising we are all one consciousness”.

Dzogchen possesses a highly developed vocabulary and practice tradition concerning awareness, emptiness, luminosity and spontaneous presence.

For practitioners, the aim is not to manufacture an improved state of mind.

It is to recognise what has been obscured by habitual perception.

Trekchö and Tögal

Advanced Dzogchen teachings sometimes distinguish practices known as trekchö and tögal.

Popular accounts often describe trekchö loosely as “cutting through the ego” and tögal as “activating light-body energies”.

The traditional systems are more sophisticated than those descriptions suggest.

Trekchö is connected with recognition and stabilisation of the nature of mind.

Tögal involves advanced visionary contemplative practices associated with luminosity and the spontaneous display of awareness.

These teachings are traditionally transmitted within specific Dzogchen lineages.

It is within this context that we encounter Tibet's most extraordinary claim.

The rainbow body.

What is the rainbow body?

In Tibetan it is generally called jalü, literally rainbow body.

Dzogchen traditions describe advanced practitioners whose realisation at death can culminate in an extraordinary transformation of the physical body.

Traditional accounts may describe the corpse shrinking dramatically or, in the most complete accounts, dissolving into light so that only hair and nails remain.

Within the tradition, rainbow body is not merely metaphor.

It is described as an actual consequence of profound realisation.

Accounts exist of named Tibetan practitioners believed by their communities to have attained it.

That makes rainbow body very different from a generic New Age “light body”.

It belongs to specific Tibetan contemplative traditions.

Has rainbow body been scientifically verified?

Not in the sense required to establish that a human physical body can literally transform into visible light at death.

Religious texts, biographies, practitioner testimony and living traditions affirm rainbow-body phenomena.

Those sources are important evidence for what Tibetan traditions teach and report.

They are not equivalent to independently documented experimental evidence of matter converting into light.

Claims that particular bodies dramatically shrank after death can also involve circumstances that are difficult to investigate retrospectively.

Two statements can therefore be held together without contradiction.

Tibetan Dzogchen traditions genuinely teach and report rainbow body.

Modern science has not established rainbow body as a verified physical phenomenon.

Why the rainbow matters even before the miracle

The idea is philosophically powerful because it takes Tibetan teachings about emptiness and luminosity to their furthest possible conclusion.

Ordinary experience tells us that matter is the solid part of reality and consciousness is the elusive part.

Rainbow-body traditions invert that intuition.

At the highest realisation, even the body is not what it appeared to be.

For believers, this is literal transformation.

For someone approaching it symbolically, the teaching can also represent the complete dissolution of the distinction between embodied form and awakened awareness.

The extraordinary claim sits at the end of a very long contemplative path.

Rainbow body is not simply another version of the modern idea of “raising your vibration”.

Light in Tibetan contemplative language

The language of clear light or luminosity appears widely within Tibetan Buddhist discussions of mind, meditation, sleep and death.

Modern spiritual culture sometimes interprets this immediately as electromagnetic energy.

That is not what the terminology automatically means.

“Luminosity” can describe the knowing or manifesting quality of consciousness within Buddhist philosophical and contemplative contexts.

It may also appear within visionary practices involving experiences of light.

The vocabulary operates at philosophical and experiential levels.

Converting every reference to light into a claim about physics loses that distinction.

Tibetan Buddhism and the idea that reality is an illusion

Buddhist philosophy is also frequently simplified into the idea that the world is unreal.

Tibetan Buddhism does not simply teach that nothing exists.

Its philosophical traditions draw heavily on Indian Mahayana ideas of emptiness, dependent origination and the absence of inherent existence.

Phenomena appear.

They function.

Actions have consequences.

But things do not possess the fixed, independent essence that ordinary perception attributes to them.

The dream becomes useful because dreams demonstrate how convincing an appearance can be without existing in the way it seems to exist.

That is very different from claiming the universe is fake.

Is Tibetan Buddhism describing simulation theory?

No.

The comparison can still be interesting.

Dream yoga challenges the reliability of appearances. Bardo teachings describe transitions in which ordinary reality loses its familiar structure. Deity yoga deliberately constructs and dissolves experienced worlds. Dzogchen questions habitual assumptions about mind and phenomena.

Simulation theory asks whether the reality experienced by conscious beings might depend on a deeper level of organisation hidden from them.

There is structural resonance between some of these questions.

But Tibetan masters were not describing computers, code or simulated universes.

Turning Buddhist philosophy into technological prophecy usually tells us more about our own age than theirs.

Tibetan mysticism and the body

It would also be wrong to imagine Tibetan practice as an attempt simply to escape the body.

Tantric Buddhism can work intensely with embodiment.

Breath, posture, visualisation and subtle-body systems involving channels and winds may form part of advanced practice.

Traditions associated with practices such as tummo, sometimes translated as inner heat, deliberately work with bodily experience in ways that can produce measurable physiological effects.

This provides an important counterpoint to the idea that Tibetan mysticism is concerned only with leaving physical existence behind.

The body can itself become an instrument of practice.

The fascination of tummo

Tummo has attracted scientific interest because some advanced practitioners appear capable of unusual forms of thermoregulation during meditation.

Popular accounts sometimes inflate this into claims that Tibetan monks can ignore physical laws or survive impossible temperatures through mind power.

The more interesting finding is that intensive contemplative training can influence bodily processes once assumed to be largely outside voluntary control.

That is remarkable without needing to become supernatural.

It also illustrates one of the recurring themes of Tibetan practice.

The boundary between mind and body is trainable.

Where Bön fits

Any broad discussion of Tibetan mysticism should also acknowledge Bön.

Modern Bön is a sophisticated Tibetan religious tradition with monastic institutions, philosophical teachings, rituals and Dzogchen systems of its own.

Older Western accounts often described it simply as Tibet's primitive shamanic religion later altered by Buddhism.

Modern scholarship presents a much more complicated history.

Bön and Buddhism influenced one another extensively, and Bön as a self-conscious organised tradition developed in a Tibetan environment already profoundly affected by Buddhism.

This is another reason to be cautious with the idea of one timeless “ancient Tibetan spirituality”.

The religious landscape evolved.

What Western occultism added

Tibet became particularly important to Western esoteric imagination during the nineteenth and twentieth centuries.

The geographical remoteness of the Tibetan plateau made it an ideal location for stories of hidden masters and secret wisdom.

Theosophy and related occult movements imagined advanced adepts living somewhere in the Himalayas.

Later writers blended Tibetan Buddhism with ideas about ascended masters, Atlantis, psychic powers and hidden spiritual hierarchies.

Some of that imagery still shapes popular ideas of Tibet today.

The historical Tibetan traditions are mystical enough without those additions.

Mystery School or living religion?

Tibetan Buddhism sometimes appears in modern lists of ancient Mystery Schools alongside Egypt and Eleusis.

The comparison is useful only up to a point.

There are initiations.

There are restricted teachings.

Teachers transmit advanced practices.

There are elaborate ritual systems and transformations of identity.

Those features genuinely resemble aspects of what modern readers associate with Mystery Schools.

But Tibetan Buddhism is not the remnant of one universal ancient secret school.

It is a vast living Buddhist tradition with scriptures, monasteries, philosophy, ethics, devotional practice, ritual, debate, art and ordinary religious life.

The esoteric practices exist inside that much larger world.

What can modern readers take from these traditions?

The most accessible insights do not require advanced tantric practice.

One is impermanence: noticing how often experience changes while the mind insists on stability.

Another is awareness of transition. Falling asleep, waking, changing roles, losing identities and entering uncertain periods all reveal how often human life moves through states of becoming.

Dreams provide another point of reflection. Even without formal dream yoga, they show how completely consciousness can inhabit an apparently real world during sleep.

And then there is mortality.

Remembering that life ends can sharpen rather than diminish it.

These are not substitutes for Tibetan Buddhist practice.

They are questions the traditions place before anyone willing to consider them seriously.

The radical proposition beneath the practices

Dream yoga, bardos, phowa, deity yoga and Dzogchen can appear to be completely different topics.

Yet one proposition runs through much of this material:

Do not wait until familiar reality collapses to discover that you never understood how it was being constructed.

Dream yoga practises recognition inside a dream.

Meditation practises recognition inside ordinary consciousness.

Bardo teachings practise recognition through death and transition.

Deity yoga exposes the constructed quality of identity.

Dzogchen asks whether awareness itself can be recognised before habitual interpretation takes over.

The systems vary enormously, but the repeated challenge is to become less automatic.

The culture that practised for death

Perhaps this is the part of Tibetan spirituality most foreign to modern Western life.

We spend extraordinary amounts of energy avoiding death psychologically.

We hide it institutionally.

We euphemise it linguistically.

We market endless ways of looking younger and extending life.

Tibetan Buddhist traditions developed practices in which death could be studied, imagined, rehearsed and incorporated into spiritual training long before the final moment arrived.

The purpose was not morbidity.

It was preparation.

If everything we mistake for permanent will eventually disappear, learning to recognise impermanence now becomes a form of freedom.

The mystery is not only in the supernatural claims

Tibetan religion contains extraordinary claims.

Some practitioners believe consciousness continues through death.

Some lineages recognise reincarnated teachers.

Dzogchen traditions report rainbow-body transformations.

Tantric systems describe subtle forms of body and consciousness that cannot simply be equated with contemporary neuroscience.

Those claims can be examined without automatically accepting or dismissing them.

But the most compelling thing about Tibetan mysticism may be something we can observe without resolving any supernatural question.

Human beings built sophisticated methods for exploring states of consciousness that most of us barely notice.

They trained during dreams.

They trained around sleep.

They contemplated death.

They deliberately constructed and dissolved identities in meditation.

They studied what happens when the structures that usually tell us who and where we are become unstable.

Whether those practices ultimately reveal rebirth, bardos or rainbow bodies remains a question of religious belief and interpretation.

What they indisputably reveal is how little attention most of us give to the transitions occurring inside consciousness every day.

Perhaps that is a sufficiently strange place to begin.
