“Without inside, without outside — the two arise as one. He who knows this needs no other teaching. He who does not — no teaching will reach him.”
— Saraha, Dohakosha (Royal Doha)
What follows is an exploration of Quantum Buddhism at its most precise — the simultaneous arising of awareness and experience, described from two directions across fourteen centuries.
Saraha didn’t write carefully constructed arguments. He sang. Wildly. Directly. In the markets and charnel grounds of 8th-century India, he pointed at the nature of mind the way you might grab someone by the shoulders and turn them to face a sunrise they were standing with their back to.
We begin with him today because what follows is not primarily a philosophical argument. It is an invitation to recognize something. The philosophy is the map. The recognition is the territory.
And the territory has a name: lhan cig skye pa.
COEMERGENCE
Where We’ve Been: Quantum Buddhism’s Foundation
In our previous post, we explored the Cauchy surface — the complete present moment, the spacetime snapshot that contains everything needed to describe the full arc of a system’s past and future. We discovered that now is not a thin sliver between what was and what will be. Now is complete. Now is the whole thing.
In another post, we explored Hilbert space — the mathematical space of all possible states of a system, the infinite field of potential from which definite experience arises at the moment of measurement. We discovered that awareness, like Hilbert space, is not a thing among other things. It is the space in which things appear.
We ended with Nagarjuna’s precision:
“Whatever is dependently co-arisen, that is explained to be emptiness. That, being a dependent designation, is itself the middle way.”
And we ended with a question:
What happens at the exact boundary between the field of all possible moments and this moment, now?
Today we answer it.
The Problem With “Collapse”
In standard quantum mechanics, the language used is “wavefunction collapse.” The state vector — holding all possibilities in superposition — collapses into a single definite outcome when measured.
This language is useful. But it is also, in a subtle way, misleading.
Collapse implies that something falls. That something which was full becomes empty. That the richness of the superposition is somehow lost when a definite experience arises.
But consider what actually happens in meditation when a thought arises.
Was the thought hidden somewhere, waiting to appear? Did it fall from a fuller state into a lesser one? Or did it simply… arise? Complete in itself, from the very beginning, carrying within it the full texture of awareness that allowed it to appear at all?
The Kagyu tradition would say: the thought and the awareness that knows it are not two separate events. They are one event, recognized from two angles.
This is not collapse. This is coemergence — lhan cig skye pa.
Lhan cig — simultaneous, together, at the same time. Skye pa — arising, birth, coming into being.
The awareness and the appearance arise together. Neither precedes the other. Neither causes the other. Neither is more fundamental than the other.
They are one movement, seen from two sides.

The Geometry of Coemergence: Quantum Physics Meets Buddhist Mind
Now let’s bring our two physics frameworks back together — because this is where the trilogy finds its resolution.
A Cauchy surface is a complete slice through spacetime. It is the present moment as a total description of reality — everything that is, right now, from which past and future can in principle, be derived from. It is the where and when of experience. The ground.
Hilbert space is the space of all possible states. It is the field of potential from which any particular experience can arise. It is the what might be of experience. The sky.
In standard physics, these two frameworks operate in different domains. Cauchy surfaces live in general relativity — the physics of spacetime, gravity, the large-scale structure of the universe. Hilbert spaces live in quantum mechanics — the physics of probability, superposition, the small-scale structure of matter. One of the great unresolved challenges of modern physics is precisely how to unite them.
But here is what is extraordinary:
In the domain of awareness, they are already united.
Every moment of experience is simultaneously both:
A Cauchy surface — a complete present moment, total in itself, carrying the entire causal history that led to it and seeding everything that will follow.
And a Hilbert state — an arising from a field of infinite potential, one specific configuration of awareness that could have been otherwise, definite now but empty of any fixed, inherent nature.
The moment you are reading this sentence is both things at once. It is a complete snapshot — total, real, undeniable. And it is an arising from possibility — contingent, empty, dependently originated.
It is a Cauchy surface emerging from Hilbert space.
It is lhan cig skye pa.
What Nagarjuna and Quantum Mechanics Agree On
Let’s be precise here, because precision matters and Nagarjuna demands it.
Nagarjuna’s central argument in the Mūlamadhyamakakārikā is that nothing possesses svabhāva — own-nature, inherent self-existence, existence from its own side independent of conditions.
This is not nihilism. Nagarjuna is not saying nothing exists. He is saying nothing exists independently. Everything that exists, exists in relationship — co-dependently, co-conditionally, co-emergently.
Quantum mechanics discovered something structurally identical in the 20th century:
A quantum system has no definite state independent of the measurement context. The electron has no definite position “from its own side.” The state vector has no single definite value until the conditions of observation meet it.
This is not a metaphor. This is not a loose analogy.
Both Nagarjuna and quantum mechanics are pointing at the same structural feature of reality: things do not have inherent existence independent of the relational conditions in which they arise.
The Cauchy surface does not exist independent of the spacetime that gives rise to it. The Hilbert state does not exist independent of the measurement that actualizes it. The present moment of awareness does not exist independent of the consciousness that meets it.
And crucially — consciousness does not exist independent of the moment it meets.
They arise together. They are empty together. They are real together.
This is the middle way Nagarjuna described: not the extreme of inherent existence, not the extreme of nothingness — but the living, dynamic, coemergent arising of experience itself.
The Kagyu Pointing-Out: Simultaneous Arising as Direct Experience
In the Kagyu lineage, there is a practice called the pointing-out instruction — ngo sprod in Tibetan. The teacher doesn’t explain the nature of mind. The teacher points directly at it, using whatever means will cause the student to recognize what has always already been present.
Consider this a pointing-out instruction in the form of physics.
Right now, in this moment of reading:
There is content — words, concepts, meaning arising. There is awareness — the knowing of those words, concepts, meaning.
Now: which came first?
Not the words — they arose within awareness. Not the awareness — it is knowing these words, not some other content. Get it?
They are not two separate things that happened to meet. They arose as one event, recognized from two angles. The content is the Cauchy surface — complete, definite, total. The awareness is the Hilbert space — open, potential, without fixed nature. And the arising of experience is neither one nor the other, but the coemergence of both.
Lhan cig skye pa.
The Third Karmapa, Rangjung Dorje, one of the greatest minds in the Kagyu tradition, described this directly in his Treatise on Buddha Nature:
“Neither arising from causes and conditions, nor without causes and conditions — the nature of the mind, from the very beginning, is the dharmakaya.”
Not caused. Not uncaused. Coemergent.
The dharmakaya — the ultimate nature of mind — is not a thing that exists somewhere waiting to be found. It is the open, aware, empty nature of this very moment of experience, recognized as it is.

The Meditation
We don’t want to end in abstraction. Saraha wouldn’t allow it.
So here is the practice that emerges from the trilogy:
Rest for a moment. Not in any special state — just as you are.
Notice the present moment — its completeness, its totality. This is the Cauchy surface. Nothing is missing. Past and future are present as traces and tendencies, but this moment itself is whole.
Notice the openness or the vastness — the fact that this moment could have been otherwise, that it arises from an infinite field of potential, that it has no fixed, inherent nature from its own side. This is the Hilbert space of awareness. Empty, open, ungraspable.
Now notice: who is noticing?
Not as a philosophical question. As a direct investigation.
Is the awareness separate from what it knows? Or do they arise together, in the same instant, as one seamless event?
If you look carefully — really carefully — you won’t find a boundary between the knower and the known. You won’t find a moment when awareness existed without content, or content existed without awareness. You cannot have one without the other. What use is the known if noone is knowing, and what use is the knowing if there is no known.
You will not find a difference in the moment that you constructed the knowing in your mind and when it dissolved into another awareness.
This movement from construction to dissolution — from generating the form to releasing it back into open space — is precisely what Vajrayana practice describes in Kyerim and Dzogrim, the generation and completion phases that structure most Tibetan meditation practices
You will find lhan cig skye pa.
Coemergence.
The Cauchy surface and the Hilbert space, meeting in this instant, as this experience, recognized by this awareness — which is none other than the experience itself, looking at itself, finding nothing separate, finding nothing lacking.
Why This Matters Beyond the Cushion
Coemergence is not just a meditation concept. It is a description of how reality actually works — and recognizing it changes everything.
When you understand that your experience and your awareness coemerge, you stop trying to fix experience and start resting in awareness. Not because experience doesn’t matter — but because you recognize that clinging to particular experiences, or pushing others away, is based on a fundamental misunderstanding. It treats experience as if it had inherent existence, as if it were a thing with its own nature, independent of the awareness meeting it.
It doesn’t. It isn’t.
Every difficult emotion is a Hilbert state — full of potential, without inherent solidity, arising from conditions that are already changing.
Every moment of clarity is a Cauchy surface — complete, total, already containing the seeds of what follows.
And the awareness that knows all of it — open, unobstructed, lhan cig skye pa — is not something you need to achieve.
It is what is reading these words right now.
The Trilogy Complete
We began with the present moment as a complete snapshot — the Cauchy surface, the ground.
We discovered the space of infinite potential — Hilbert space, the sky.
And today we recognized what happens between them, or rather what has always been happening as them:
The simultaneous arising of awareness and experience, ground and sky, emptiness and appearance.
Physics calls it the measurement problem — the great unsolved mystery of how quantum possibility becomes classical actuality.
Nagarjuna called it dependent origination — the arising of all phenomena in mutual, simultaneous dependence.
Saraha sang it from the charnel ground — without inside, without outside, the two arise as one.
The Kagyu tradition names it lhan cig skye pa — coemergence — and points to it as the very nature of mind itself, never absent, never hidden, only unrecognized.
Now it has been recognized.
What you do with that recognition — that’s the practice of a lifetime.
