Mandukya Upanishad: Why Words Cannot Reveal the Self

The Mandukya Upanishad is the shortest of the Upanishads, drawn from the Atharva Veda, and it works by taking the syllable Om apart into three parts that match the waking, dream, and deep-sleep states of experience. In this sixth class of an eight-part series, Swami Tadatmananda, a traditionally trained teacher of Advaita Vedanta, takes up the seventh mantra, which he calls the main mantra of the text. The puzzle at its center is a hard one: if the self, atma, is pure consciousness, and if consciousness is already present in every experience, then what can teaching possibly add? His answer is that the teaching does not reveal the self at all. It removes the mistaken ideas that hide it, and it does so largely through a relentless sequence of negations, with a handful of words that sound positive but turn out to be negations in disguise.

What is the seventh mantra doing, and why is it mostly negative?

The class opens by reviewing where the previous session ended. The mantra is built as a string of denials. Consciousness is not the consciousness of the dream state, not the consciousness of waking, not the consciousness that sits between the two, and not the consciousness of deep sleep. It is not "simple consciousness," and it is not unconsciousness. It cannot be seen, grasped by the organs, inferred by logic, or made into an object of thought. The teacher's point, repeated across the session, is that nearly every term in the statement is a negative. Even the terms that sound affirmative are doing negative work.

That is the sort of observation that can sound like a riddle until you see the logic behind it. Vedanta distinguishes between things that can be known through their qualities and things that cannot. Words are good at revealing qualities, actions, kinds, and relationships. Atma has none of those in the sense that a pot has a shape or a color. So words, in the strict sense, are useless for pointing to it.

Why can't words reveal the self, and what are they for then?

The teacher is blunt about this. In the question period, he says, the class made the point very clearly: words cannot reveal atma. But he adds the reassurance that makes the whole method make sense. Words do not need to reveal atma, because revelation is only necessary for something that is absent. Something already present in your experience does not need to be brought to light.

"Words cannot reveal atma. And fortunately, words need not reveal atma."

— Swami Tadatmananda, sixth class of the Mandukya Upanishad series (Arsha Bodha Center; the class was originally taught in 2011), around 4:05 in the video

So what are the teachers doing? The answer he gives is one of the cleanest statements of the method in the whole session:

"We're not teaching atma. We're teaching you to destroy the wrong thinking about atma. That's really what Vedanta is all about."

— Swami Tadatmananda, same series, around 5:05 in the video

This reframes the purpose of the negations. They are not describing a hidden object that you then have to find. They are dismantling the false images you have layered over something you already are. The teacher returns to a metaphor from the Arundhati-star tradition, which he calls the arundhati-darshana method. Imagine searching the night sky for a particular star. You know it is somewhere in your field of view, but you do not know which point it is. A careful method of elimination, ruling out one candidate after another, leads you to the star you were looking for. The star was never absent; it was unidentified.

"That star is present in your field of view but you don't know which it is."

— Swami Tadatmananda, same series, around 6:00 in the video

Consciousness works the same way. It is present in every experience, but it is not recognized as what it is. The sequence of negations is a method of elimination. Each denial removes one thing consciousness is not, until what remains is what was there all along.

What does "negation in disguise" mean?

The most interesting move in this class is the teacher's treatment of the final compound in the mantra, the word that he says is the only one in the whole statement that is positively meant. He resolves it as "the essence of a thought." The word pratyaya means a thought or a mental activity, and the second element means essence or content. He offers an analogy familiar from ordinary life. The content of a wave is water. The content of a clay pot is clay. What, then, is the content of a thought? The answer he gives is consciousness, the one self that is present in every mental activity.

He pushes the idea further. Waking has thoughts, and dream has thoughts. Can you speak of a thought during deep sleep? He suggests, somewhat theoretically, that deep sleep can be understood as a single thought whose form is pure ignorance. Whatever the theoretical framing, the point holds: consciousness is the content in each of the three states, the thread running through all of them.

Here the teacher draws on Shankara's commentary, which reads the word differently. Shankara takes it to mean that which follows, that which is continually present. The teacher's gloss is simple: something is present through waking, dream, and deep sleep alike. And that is where the negation in disguise appears. A statement that seems to affirm the self as present is, in its structure, denying that the self could come and go, could be absent in one state or altered in another. Something that looks like a positive claim is actually ruling out an alternative.

"Is that necessary? You already see me. You already know me."

— Swami Tadatmananda, same series, around 11:30 in the video (pointing out that pointing to himself is unnecessary)

The illustration of pointing to himself is deliberately ordinary. Nobody needs to be shown that the teacher is sitting in front of them. The word for the self plays the same role. It is unnecessary to point out the existence of consciousness, because consciousness is the one thing you cannot step outside of in order to check.

How do you see the three states as they appear to a witness?

The teacher returns to a teaching device he has used throughout the series: the movie theater. The waking, dream, and deep-sleep states are features on a screen, coming and going, while a conscious being sits in a comfortable chair eating popcorn, watching them all. The screen changes. The viewer does not. The question the class keeps asking is who undergoes the three states, and who is the conscious being observing their alternation. Remembering that witness is the key to seeing why the statement points to something stable beneath changing experience.

This is also why the Om analogy in the Upanishad works. The three syllables of Om correspond to the three states, and the silence after them points toward what is not one of the states at all. The class is less about the metaphysics of Om than about training attention to notice the one observing every state.

Why is "I am a conscious being" the only self-established fact?

The mantra uses the Sanskrit word siddha, meaning self-established: a fact that stands without needing anything else to prove it. The teacher walks through the candidates one by one. The world is not self-established, because you need sight, hearing, taste, smell, and touch to know it. Your body is not self-established for the same reason. Even the mind is not self-established, because the mind and its activities are themselves known through consciousness. Each apparent foundation turns out to rest on something further.

"There are very few things in life which are self-established."

— Swami Tadatmananda, same series, around 13:20 in the video

What survives the elimination is the simplest possible statement: I am a conscious being. I exist as a conscious being. Nothing needs to prove it, and it cannot be proven by anything more basic than itself. You cannot step outside your own awareness to check whether it is there.

What remains after all the negation?

The class closes with a sequence of images that make the point through contrast. The teacher holds up clay in one hand and a pot in the other, asking what the pot really is. Its shape is a name given to clay. A rope mistaken for a snake is a useful image for the way the three states are projected onto consciousness because of ignorance, and the rope is the only thing that was ever real. The teacher is careful about the limits of the analogies, and he tells students to see them as ladders to be set aside once the point is reached.

What remains, in the end, is not an object but a presence: the consciousness that is already present in your experience, known as it truly is. The Sanskrit word for this non-duality, advaita, appears at the close of the mantra. Between the opening Om shanti and the final prayer for peace, the class repeats the invocation three times, a small liturgical frame around a long argument about why the thing you are looking for is the looking itself.

Where to go from here

If this class has you curious, start with the sequence rather than the single mantra. The seventh mantra is the centerpiece of a compact text, and the teacher's earlier sessions on negation and on the three states supply the vocabulary the class assumes. The videos in this series are more useful with the Sanskrit, Roman transliteration, and translation on screen, which the volunteers Jhanvi, Vikram, Upendra, and Mangesh produced for these classes. The Arsha Bodha Center's website, arshabodha.org, offers more on the teacher and the wider teaching program.

Then try the teacher's own test. Notice one experience right now, and ask what in it is self-established, and what depends on something else. Most of what you find will fall into the second category. The first category is smaller than you expect, and the teacher's claim is that it is enough.
