The mind is not a thing but an interaction: it arises the moment you come to know something. To understand mind clearly, it helps to separate two elements that are usually blurred together — what is known, and the knowing of it.
How the Mind Arises
The mind arises as you come to know. Before knowing, there is no mind in any active sense; the moment awareness senses an object, mind flickers into being as the relationship between knower and known. Consider a child hearing thunder for the first time: before the sound, there is only pure alertness; the instant the sound registers, the mind arises as the knowing-of-thunder. What is known in that moment is substance — thought, energy, and matter, the raw material of experience. The thunderclap is matter and energy; the child’s startled feeling is thought. Mind, then, is simply the awareness of substance, not substance itself.
Awareness Without Substance
This gives us the core claim: the mind is awareness, and awareness has no substance of its own. Awareness is like a clear light shining on objects — the light reveals the objects but is not made of them. A well-known analogy is a mirror reflecting a passing procession of people: the mirror shows every face perfectly, yet holds none of them; it remains unchanged whether the procession is joyful or somber. Awareness functions the same way toward thought, energy, and matter.
Identification: The Primary Error
The primary error is to mistake this awareness for having substance — to imagine that the mirror is somehow made of the faces it reflects. This error is called identification, the belief “I am that”. A person who feels angry and says “I am angry” has identified awareness with a passing mental formation, as though the mirror had become the angry face it briefly reflected. Spiritual traditions repeatedly warn that even identifying with subtler states — like calling oneself “the observer” or “consciousness” — can become another disguised form of this same error.
The Impulse Toward Harmony
Yet mind is not merely a passive mirror; it carries an impulse. The mind is the impulse of awareness to bring harmony to all substance — to resolve the friction, contradiction, and disorder that arise among thoughts, feelings, and physical events. This is why an unsettled thought naturally seeks resolution, and why a body in pain naturally seeks equilibrium: awareness, through mind, continually works to bring coherence to the substance it observes.
Emptiness as the Corrective Insight
The Buddhist concept of emptiness (sunyata) addresses exactly this problem. Emptiness simply means that awareness is empty of substance — it has no inherent form, feeling, or matter of its own, and is not a fixed, separate entity clinging to any content. Far from being a bleak or nihilistic idea, emptiness is understood in Buddhism as liberating: because awareness holds no fixed identity, it is not trapped by any single experience, thought, or sensation. Emptiness corrects the error of identification by revealing that awareness was never “the angry face,” “the thought,” or “the body” — those were always just passing content, while awareness remained the clear dimension in which they appeared.
Neti, Neti: Neither This, Nor That
The Vedantic method of neti, neti — “not this, not that” — expresses the same realization from a different tradition. In this practice, one examines every experience — a sensation, an emotion, a thought, even the sense of being a body — and says “neti,” not this, negating it as the true self. The sage Yajnavalkya, when pressed to define Brahman (ultimate reality), famously refused every description and simply answered “neti, neti,” clearing away every possible misidentification until only the pure, witnessing awareness remained — the one thing that could never itself be negated. This is not a rejection of the world but a systematic disentangling of awareness from the substance it observes.
Two Independent Dimensions
In mathematical terms, awareness and substance behave like two independent dimensions or axes, comparable to length and time in physics — each can vary without forcing a corresponding change in the other. Substance changes constantly along its own axis: thoughts form and dissolve, energy shifts, matter transforms. Awareness, on its own axis, simply observes this movement without itself moving through the same changes. Confusing these two independent dimensions — treating a shift in substance as a shift in awareness — is, in this framework, the root of all confusion.
The Five Aggregates as Substance
Buddhist psychology describes five aggregates: form, feeling, perception, mental formations, and consciousness itself, all understood as manifestations of substance rather than fixed, permanent essences. Each of these aggregates is impermanent, arising and passing according to causes and conditions. A feeling of joy arises, colors experience for a while, and dissolves, much like a wave rising and falling on the surface of water; even consciousness, as a stream of mental events, belongs to this changing substance rather than to unchanging awareness itself.
The Root of Illusion
Because these manifestations are always in flux, and because awareness itself simply observes that flux, the basic illusion arises precisely when awareness mistakenly thinks it is changing. Imagine a movie screen: images move rapidly across it, characters age, seasons shift, storms rage — yet the screen itself never travels anywhere, ages, or gets wet. If the screen “believed” it was doing the traveling, aging, or getting wet, that would be the illusion in miniature. This is the deeper layer beneath identification: not just claiming “I am this thought” but subtly assuming “I, awareness, am undergoing this change,” when in truth it is only the substance that changes while awareness remains the constant witnessing dimension.
Seeing the Unconditioned
When this relationship between awareness and substance is finally understood — that awareness quietly observes while only substance moves and transforms — everything can be seen in its unconditioned nature, free from the labels and distortions identification had layered over it. A thought is then just a thought, a pain is just a sensation, a feeling is just a passing wave, none of them commandeering the identity of the one who sees them. This is the practical value shared by emptiness and neti, neti alike: not an abstract philosophical exercise, but a direct dismantling of the confusion between the eternal, unchanging witness and the ever-shifting world it silently illuminates.
The Main Ideas
- The mind arises as you come to know.
- What you come to know is substance (thought, energy and matter).
- The mind is the awareness of substance.
- In other words, the mind is awareness; and it has no substance itself.
- The primary error is to think that mind has substance. This error is called IDENTIFICATION.
- The mind is the impulse of awareness to bring harmony to all substance.
- The concept of EMPTINESS in Buddhism simply means that awareness is empty of all substance.
- Emptiness corrects the error of identification.
- Identification is the error of thinking, “I am that.”
- Emptiness is the realization of “Neti, neti” meaning, “I am neither this, nor that.”
- In mathematical terms, awareness and substance are two dimensions that are independent of each other.
- The basis of all confusion is awareness identifying itself with substance.
- All forms, feelings, perceptions, mental formations, and consciousnesses are manifestations of substance.
- These manifestations of substance are subject to change. Awareness is simply observing this change.
- The basic illusion comes about when awareness thinks it is changing.
- When you realize what awareness is in relation to substance you then are able to see everything in its unconditioned nature.
