What This Concept Is About
In the completion-stage practice (圓滿次第, saṃpannakrama, "completion stage") of Anuttara Yoga (無上瑜伽, anuttarayoga, "unsurpassed yoga"), the three emptinesses (三空, tri-śūnya, "three emptinesses") are not an abstract philosophical meditation but three stages actually experienced by the practitioner in the process of withdrawing consciousness. The keywords here are the three minds — 明 ("clarity"), 增 ("increase"), and 得 ("attainment") — three states of mind's manifestation that together form a process of progressively deepening, layer-by-layer withdrawal.
We can imagine consciousness as a crystal with multiple layers of structure. The outermost layer is coarse consciousness — our everyday thoughts, emotions, and sensory judgments. Beneath these coarse activities lie increasingly subtle layers of mind. The three emptinesses refer precisely to the three deep states of consciousness that the practitioner enters in sequence after stilling the coarse activities of mind.
明心 ("clear mind") is the first stage. Most coarse thoughts have already ceased, yet the mind retains the capacity for clear awareness. It is like a windless lamp flame — settled and luminous: knowing without content, awareness without an object, only pure luminosity.
增心 ("increased mind") is the second stage. The mind withdraws further, and the sense of clarity itself intensifies — but this intensification is no longer clarity in the sense of "becoming clearer"; it approaches pure luminosity as a spreading whiteness, like moonlight filling an autumn sky. At this point, even the subtle mental effort of "I am observing" has faded away.
得心 ("attained mind") is the third stage. The withdrawal of consciousness reaches its extreme, and luminosity turns into a dark appearance, like an autumn sky without clouds, purely transparent — but here one must make a crucial distinction: the "darkness" of the attained mind is not the darkness of dullness or ignorance; it is the ultimate stillness that transcends the duality of light and dark. It no longer distinguishes "luminous" from "not luminous." This state is very close to the appearance of the clear light of death (死有光明) or to the level of the subtlest mind (極細心) in deep sleep.
These three stages together are called the three emptinesses — here, "emptiness" is not the nothingness of "empty of all things," but means that the coarse activities of consciousness have dissolved, giving way to deeper states of awareness. It is a process of "peeling away layer by layer." After the three emptinesses there is a "fourth emptiness," namely luminosity (光明) — the ultimate nature-luminosity of mind that can appear only on the basis of the three emptinesses.
The key point is: the illusory body (幻身, māyādeha, "illusory body") is accomplished after the three emptinesses. The illusory body is not an imagined image; it is a phantom-like body-form that arises anew from luminosity after undergoing the withdrawal of the three emptinesses — it is the direct manifestation of realizing emptiness, the "illusory body" that the practitioner manifests from the subtlest consciousness. According to the teachings of the *Pañcakrama* (《五次第論》) and the *Stages of the Path of Mantra* (《密宗道次第》), a practitioner must first realize the sequential experience of the three emptinesses before entering the luminosity of the fourth emptiness and thereby accomplishing the illusory body. This is why the three emptinesses are regarded as the crucial threshold in the entire completion stage of Anuttara Yoga — they are at once the completion of consciousness withdrawal and the starting point of higher realization.
A Walk-Through in Everyday Life
From "Scrolling on Your Phone" to "Putting the Phone Down"
Imagine this scene: you come home after overtime, exhausted, collapse onto the sofa, and start scrolling through your phone. This is a very typical contemporary state — the mind is still running at high speed, short videos one after another, an endless feed of information. At this moment, your consciousness is at its coarsest level: thoughts flying, emotions rising and falling, judgments never stopping.
Now imagine you put the phone down. Not because you want to "practice," but because you are simply too tired and your eyelids are starting to droop. You close your eyes — not sleeping, not thinking. What do you find?
For the first minute or two, the mind is still replaying what you just saw: a piece of news, an image, an unread message. These are the after-ripples of "previous thoughts"; the coarse consciousness is still running on inertia. But gradually, if the environment is quiet and the body relaxed, these thoughts begin to ebb. You enter a state of "not thinking about anything, but knowing that you are here" — clear and lucid, rather like the moment just after waking up, when the mind is still clean and empty.
This state is already very close to the prototype of 明心 ("clear mind").
But note: you are not asleep; consciousness is awake. Nor have you "entered deep meditation" — you simply put down your phone and let the mind be quiet for a moment. Yet in that moment, you have already slipped from the coarsest level of consciousness into a slightly subtler one. The essential point of the clear mind is: coarse thoughts cease, but clarity remains.
From "Awake" to "Falling Asleep"
Now, keep going. If you are truly sleepy and slide down along this clear state, what happens?
You yawn, the body sinks slightly, and awareness begins to blur — you are about to fall asleep. At this point, if you retain even a sliver of awareness, you will notice: the "clear, lucid knowing" you had before is changing. It is no longer so distinct, yet it has not disappeared. It has become a kind of hazy, diffuse awareness, as if a veil had been draped over everything — you know a little of everything, but nothing with certainty. You faintly hear the television, faintly sense the position of your body, but it all feels very distant, very blurred.
This transitional state can be roughly compared to 增心 ("increased mind").
Of course, the ordinary process of falling asleep is too fast; most people slide from wakefulness into sleep in an instant, and this transitional state lasts only a few seconds. But in Anuttara Yoga practice, the practitioner deliberately extends and stabilizes this state — not by falling asleep, but by maintaining awareness at this subtle level. The essential point of the increased mind is: consciousness withdraws further, yet a "knowing" remains — only now this "knowing" has already transcended the distinctions of bright and dark, existence and non-existence.
From "Falling Asleep" to "Deep Sleep"
If you really fall asleep and enter deep sleep — no dreams, no thoughts, and you wake up the next morning feeling like "I slept straight through till dawn" — what kind of state is that?
From a modern scientific perspective, you are probably in slow-wave sleep, with activity reduced in many regions of the brain. But what do you yourself know? Nothing. No dreams, no sense of time, no sense of space.
This state of deep dreamless sleep bears a structural resemblance to 得心 ("attained mind").
But a crucial difference must be pointed out here: the attained mind is not "being asleep"; it is experiencing this extremely subtle level of consciousness while awake. For an ordinary person, this level is only passed through unconsciously in deep sleep; for a practitioner, the task is to "enter the level of sleep while awake" — that is, to have both the complete withdrawal of deep sleep and the presence of awareness. This is extremely difficult, because in ordinary experience the two conditions are mutually exclusive: once withdrawn, there is no awareness; once there is awareness, withdrawal is not yet complete.
This is precisely the core difficulty of the three-emptiness practice, and also its core meaning — it trains a person to transcend the dual structure of ordinary consciousness (wakefulness and sleep, being and non-being, light and dark) and enter a deep state of consciousness that is neither of the two yet contains both.
A Common Mapping Mistake
Many people understand the three emptinesses as "just falling asleep" or "just spacing out." This is wrong. The key to the three emptinesses is not that "consciousness disappears," but that "the mode of operation of consciousness changes" — from a mode of "grasping outward objects" to a mode of "abiding in itself." Sleep and spacing out are unconscious slips into these states; the three emptinesses are an intentional entry into them.
An analogy: you are in a room where all the lights are on (coarse consciousness), and you can see everything clearly. Practicing the three emptinesses is not turning off the lights, but gradually dimming them — yet throughout the dimming, you always know the state of the room. Finally, the lights seem to go out completely, but you still "know" the darkness — this very "knowing" is the awareness of the attained-mind level.
This is why the classics speak of 明、增、得 ("clarity, increase, attainment") — clarity means the light is still on, increase means the light is dimming, attainment means the light seems to have gone out — but the observer has never left.
Why Contemporary People Need It
In the contemporary world, the mental state of the vast majority of us is "only going out, never coming in" — always projecting outward, always grasping at information, emotions, and stimulation. Phone notifications, social media, work pressure, the tensions of interpersonal relationships... we expend the energy of consciousness in an endless series of "outward reactions."
The value of the three emptinesses is that they teach us that consciousness is not one-dimensional. Beneath the coarse consciousness of "outward reaction" lie deeper, quieter, subtler layers. These layers are normally invisible, but they are always there — in sleep, in the moment of death, in the deepest meditative states. They are not "nonexistent"; we have simply never learned to know them consciously.
This brings three insights that contemporary people especially need:
First, the depth of consciousness far exceeds your imagination. You think "I" is the "I" that scrolls through a phone, that worries, that thinks, that judges. But the practice of the three emptinesses reveals that this "I" is only the foam on the surface of consciousness. Beneath the foam is the deep sea, and the deep sea is your true ground. Knowing this ground gives you a completely new understanding of "who I am" — you no longer so readily identify with surface thoughts and emotions, because you know they are only the surface.
Second, death can be understood rather than feared. In the Anuttara Yoga tradition, one core meaning of the three-emptiness practice is to simulate the process of death — because the order of consciousness withdrawal at death is precisely the sequence from coarse to subtle: clarity, increase, attainment. If you have become familiar with this process during life, you can maintain awareness at death and not be lost in fear and confusion. This is especially meaningful for contemporary people — we avoid talking about death, and for that very reason have never prepared for it. The three-emptiness practice offers a unique way of facing death: not as "the end of everything," but as the natural process by which consciousness unfolds its deepest levels.
Third, deep relaxation and inner peace. In the gaps between phone scrolling, in the late hours of overtime, on the subway during the commute, we have all longed for a state of "not having to think about anything." But "not having to think about anything" is not the same as "doing nothing" — it requires an inner skill, a conscious letting go. The three-emptiness practice is precisely the systematic training of this skill: not forcing yourself not to think, but letting consciousness withdraw naturally, layer by layer, returning to its original quiet state.
From the perspective of contemporary cognitive science, we can point out by analogy: the brain has different states — waking, light sleep, deep sleep, REM sleep — each with distinct neurophysiological features. The experiential states of the three-emptiness practice are likely associated with certain deep relaxation states of the brain. But here one must remain restrained: science has not proven that "the three emptinesses are some brain state." A brain state is only the physiological accompaniment of the three-emptiness experience, not the three emptinesses themselves. The three emptinesses are a subjective, conscious experience whose full meaning can only be understood within the practice tradition.
Common Misreadings and Clarifications
Misreading one: the "emptiness" of the three emptinesses means "nothing at all."
This is the most widespread misunderstanding. The "emptiness" of the three emptinesses is not "empty nothingness" — not that everything ceases to exist — but the dissolution of the coarse activity of consciousness. Consciousness withdraws from the coarse to the subtle; the coarse levels become "empty," but the deeper levels remain. It is like a building: the first, second, and third floors are all empty, but the basement is still there — the three emptinesses are "the upper floors are empty," not "the whole building is gone." More precisely, the "emptiness" in the three-emptiness experience is "a change in the mode of appearance" — not that objects disappear, but that the cognitive mode itself undergoes a fundamental transformation.
Misreading two: the three emptinesses are just a "relaxed state" in meditation.
No. The three emptinesses are not ordinary relaxation, not "calm after deep breathing," not the blankness of "thinking of nothing." They are a highly systematic meditative experience in the completion stage of Anuttara Yoga, with strict stages and criteria for verification: each of the three minds — clarity, increase, attainment — has specific experiential features and methods of verification. Ordinary relaxation is only a slight quietness at the shallow level of consciousness, nowhere near touching the level of the subtlest mind. Equating the three emptinesses with "relaxation" or "calm in meditation" is like equating Mount Everest with the little dirt mound outside your door.
Misreading three: the "emptiness" of the three emptinesses is the same "emptiness" as the Madhyamaka (中觀) concept of emptiness (空性, śūnyatā, "emptiness").
These are two different levels of concept, though ultimately related. Madhyamaka emptiness is the philosophical truth that all things lack self-nature and are empty by virtue of dependent origination; the "emptiness" of the three emptinesses is an experiential description in the process of consciousness withdrawal — the experiential fact that "the coarse activity of consciousness has dissolved." The three-emptiness experience can serve as a supporting condition for understanding emptiness, but the three emptinesses themselves are not emptiness. It is like a person who climbs to the top of a mountain and gains a wide view — but what he sees is not "the nature of the mountain." What he sees are the mountains and the earth; "the nature of the mountain" requires deeper wisdom to discern.
Misreading four: the three emptinesses are a "death experience."
The three emptinesses bear a structural resemblance to the process of death — both are a withdrawal of consciousness from coarse to subtle — but there is a fundamental difference between the two: death is an unconscious, forced withdrawal; the three emptinesses are a conscious, voluntary withdrawal. The practitioner entering the three emptinesses retains awareness, whereas an ordinary person at death loses consciousness at some stage of the withdrawal. One could say the three emptinesses are a "death practice with awareness," but not "actual death."
Misreading five: the three emptinesses are a "mystical experience" unique to the tantras, unrelated to everyday life.
The practice of the three emptinesses originates in the Anuttara Yoga lineage and indeed has its own specialized methods and conditions of transmission; it is not something anyone can "cultivate" on their own. But the structure of consciousness it reveals — the stratification of coarse consciousness, subtle consciousness, and the subtlest consciousness — was not invented by the tantras; it is a fact of consciousness itself. Each of us, in falling asleep, waking, emotional agitation, or deep concentration, experiences the transitions of these levels, without realizing their significance. The three-emptiness practice merely makes this natural process conscious, aware, and sequential. What it ultimately leads to is the recognition of the full scope of consciousness — and knowing one's own consciousness has never been the concern only of practitioners; it concerns everyone who wants to understand "who I am."
The concept of the three emptinesses is, in the final analysis, a map of consciousness. It tells us: the mind you take to be the "whole" is only the tip of an iceberg. Beneath the iceberg lies fathomless seawater — not nothingness, but a truer, more fundamental you. To know it, you need not leave everyday life — only, in every moment you put down your phone, in every instant between waking and sleep, gently and with awareness, look inward.
