People who have had near-death experiences and people who have spent years in deep meditation are often describing the same thing. They use different words. They come from different cultures and different centuries. But when you lay the phenomenological reports side by side, the overlap is undeniable. And the Tibetan tradition, more than almost any other, developed a precise technical language for exactly what happens in these threshold encounters.
This is not just interesting from an academic standpoint. If these accounts are pointing at something real about the structure of consciousness, then what we are looking at is the single most important thing a human being can know about themselves.
What NDEs and Mystical Experiences Share
The core features that show up again and again across near-death experiences are remarkably consistent regardless of the cultural background of the person. There is typically a dissolution of the ordinary sense of self. There is an encounter with light, often described as overwhelming in its vividness and intensity. There is frequently a sense of knowing, a direct perception rather than inference. And there is almost universally a quality of what people describe as love, though that word sometimes seems too small for what they mean.
The Tibetan teaching on the bardo of dying, the transitionary state that arises at the moment of death, has a specific technical term for what is encountered at the deepest moment of this process. They call it the clear light of the dharmakaya. The great luminosity. And they say it is none other than the nature of your own mind, appearing in its unconcealed, unobscured form for the first time without the veil of the physical body's filtering apparatus.
The Ocean of Ten Billion Suns
I died when I was 18. I had a near-death experience, and what happened in that experience is the most difficult thing I have ever attempted to put into language. But I will try, because it is directly relevant to everything I teach.
When the senses and the perception of my body and individuated consciousness turned off, what arose in their place was this: an infinite ocean of eternity, of ten billion suns. That is the closest I can come to it. It was literally eternity, infinity, pure light. And you are that. There was no recollection that I had ever lived. No recollection of ever being born. No sense of time whatsoever. Total. I cannot even call it bliss or love. It was just the Beyond.
Years later, after awakening had occurred, I brought this experience to Peter Brown. Peter was one of my most important teachers, a man who had been living in continuous awakening for over twenty-five years. I asked him whether that experience was something I should be able to enter at will, something I should be able to cross my legs and return to.
His response changed everything.
He said: now tell me, was it or was it not an experience?
I sat with that. And I said: it is definitely an experience.
He said: that is right. Your mind is the dharmakaya. It appears as all states. It appeared as that ocean of ten billion suns the same way that your presence, your nature, is appearing as this room, this conversation, right now. It is the same thing. It just looks different. In that plane, in those more fundamental levels, it is configured as infinity, eternity, pure light. Here, it is configured as this.
What the Tibetan Tradition Says About This
The Tibetan teaching on the bardo of dying describes what happens at the moment of death with a precision that can seem almost clinical if you approach it as an outsider. But from the inside, from the perspective of having had the encounter, it reads like a detailed map of a territory you have already visited.
At the moment of death, the physical elements that constitute the body dissolve in sequence. As they dissolve, the ordinary discursive mind, with all its commentary and storytelling and grasping, dissolves with them. What remains when the ordinary mind is gone is the clear light, the dharmakaya, the nature of mind in its unobscured condition.
The text is explicit that this clear light is not something foreign or external. It is your own nature. It has been present all along, obscured by the movement of thoughts and perceptions and the sense of being a separate self. At death, that obscuration is temporarily removed. The question is whether you recognize it.
If you recognize it, if you know that this vast luminosity is none other than your own nature, you are liberated in that moment. If you do not recognize it, if you encounter this light and take it to be something outside yourself, something alien, something terrifying, or simply if you are so disoriented by the process of dying that recognition is not possible, then the chain of conditioning continues and another birth is taken.
States Versus Nature: The Critical Distinction
Here is where the teaching gets important in a way that is easy to miss. Having an NDE is not the same as awakening. Having a mystical experience is not the same as awakening. Even having an experience of what appeared to be infinite pure consciousness is not, by itself, a permanent change in your relationship to reality.
Peter Brown was extremely clear about this. He pointed out that mystical states, silence, samadhi, bliss, satori, the ocean of ten billion suns, all of these are conditioned phenomena. They are configurations of consciousness. They are states. They arise and they pass. Your nature is that which they arise in. Your nature is not any particular state.
If you set up the appropriate conditions, you can have those experiences. The cessation of ordinary perceptual functioning combined with a trigger like physical trauma or extreme depth in meditation can produce access to these vast luminous states. But having the state and knowing the nature of that state as your own nature are two different things.
This is what the Dzogchen and Mahamudra teachings mean when they distinguish between experience and realization. Experience is something that happens to you. Realization is a change in your fundamental understanding of what you are. Experience can be a catalyst for realization. But it is not the same as realization.
The direct perception, the dawning understanding that the same consciousness that appeared as that ocean of ten billion suns is appearing right now as this ordinary moment, as the sound of traffic or the sensation of sitting, that is realization. And that is what Peter was pointing at.
What NDEs Tell Us About the Nature of Consciousness
What makes near-death experiences important as data is that they suggest consciousness is not what the standard materialist account says it is. In that account, consciousness is a product of the brain. When the brain's activity ceases, consciousness ceases. The NDE points in a different direction. When the brain's ordinary processing stops, consciousness does not stop. What stops is the ordinary filtering and structuring of experience. What remains is something vast.
The Tibetan teaching says this is because consciousness is not produced by the brain. The brain, and the body it runs, is a vehicle for consciousness. It is how a particular configuration of the dream, namely this human life in this space-time framework, is maintained and navigated. But the consciousness that uses the vehicle is not reducible to the vehicle. It precedes it and continues beyond it.
This is not a claim about the survival of the personality. The personality, the character, the accumulation of memories and preferences and tendencies that constitutes who you ordinarily think you are, that is not what survives or what is encountered in the clear light. What is encountered is something much more fundamental. In my own NDE, there was no recollection that I had ever lived. No sense of Ryan. Just the vast open luminosity of awareness itself.
How Practice Helps You Recognize What NDEs Reveal
The reason the Tibetan tradition developed these teachings was not primarily for the moment of death, though they absolutely apply there. The reason was to help practitioners recognize the clear light while still alive, so that when it arises at the moment of death, recognition is not being attempted for the first time under the most extreme conditions imaginable.
The clear light is not only available at death. It arises every night in dreamless sleep. It is present right now as the ground of this reading, of this moment. What the practice does is develop the capacity to recognize it, to see it, to know it as your nature rather than as something alien or occasional.
Dream yoga is training in recognizing the dream state for what it is. That same recognition, applied more subtly, is training in recognizing the nature of all experience as the display of the clear light, as the play of the dharmakaya. When that recognition stabilizes, the encounter with the clear light at death is not terrifying. It is a homecoming.
The Tibetan Book of the Dead states explicitly that if you exit the body in a state of awareness seven times, ascertaining the clear light, you will without doubt be liberated in the transitionary period. That is not a metaphor. It is a specific claim about what is possible through disciplined practice in this lifetime. The NDE shows us what is available. The practice is how we learn to meet it with open eyes.
