Mandukya Upanishad — The States of Consciousness

Imagine you are watching a movie in a theater. Sometimes you are so absorbed in the film that you forget you are sitting in a seat — you laugh, cry, and feel afraid as if everything on screen is happening to you. But if you pause and look around, you remember: you are the one watching. The Mandukya Upanishad teaches us something similar about our own awareness.

The Mandukya Upanishad is the shortest of the major Upanishads — just twelve verses — yet the great sage Muktikā declared that if a seeker could study only one Upanishad, this alone would be enough for liberation. It is that powerful. Its central teaching revolves around a single sacred syllable that you have probably chanted many times: AUM (often written as Om).

So what makes AUM so special? The Mandukya reveals that the three sounds within AUM — A, U, and M — correspond to three states of consciousness that every human being experiences every single day.

The First State: Waking (Jāgrat) — The Sound 'A'

Right now, as you read this, you are in the waking state. The Upanishad calls the Self in this state Vaishvānara. In this state, your senses are turned outward. You see the world around you, hear sounds, taste food, and interact with other people. You experience the physical universe. Most people assume this is the only "real" state, but the Mandukya invites us to look deeper.

The Second State: Dreaming (Svapna) — The Sound 'U'

Every night when you dream, you enter a completely different world. In your dream, you might fly over mountains or talk to people who are not really there. The Upanishad calls the Self in this state Taijasa, meaning "the luminous one," because in dreams, your mind creates an entire world of light and experience from within itself. No external sun is needed — your consciousness is the light source. This shows us that the mind has incredible creative power.

The Third State: Deep Sleep (Suṣhupti) — The Sound 'M'

In deep, dreamless sleep, all thoughts, worries, and images dissolve. You are not aware of anything at all — no world, no body, no name. The Upanishad calls the Self in this state Prājña, meaning "the one of deep knowledge." Even though it seems like nothing is happening, this state is actually a doorway. It is a state of bliss — which is why you feel refreshed after deep sleep. All experiences merge into a kind of seed form here.

The Fourth State: Turīya — The Silence After AUM

Now here is the most profound teaching. After you chant A-U-M, there is a moment of silence. That silence represents the fourth state called Turīya, which simply means "the fourth." Turīya is not really a state like the other three — it is the awareness that witnesses all the other states. It is the screen on which waking, dreaming, and deep sleep are projected, like a movie screen that remains unchanged no matter what film plays upon it.

Turīya is your true Self, the Ātman. It cannot be seen, touched, or grasped by the senses. It is not the experiencer of waking life, not the dreamer, and not the blankness of deep sleep. It is pure consciousness itself — unchanging, peaceful, and infinite. The Mandukya boldly declares: this Ātman is Brahman, the ultimate reality of the universe.

Why Does This Matter to You?

Think about it this way: every night, you pass through all three states without even trying. You are already traveling through these realms of consciousness. The Mandukya Upanishad simply asks you to become aware of the traveler — the silent witness who is present in all states but is not limited by any of them.

Next time you chant AUM, try this: give full attention to each sound — A emerging from your throat, U rolling through your mouth, M humming at your lips — and then rest in the silence that follows. In that silence, you are touching something the ancient rishis considered the highest truth: you are not just the body, not just the mind, not just your thoughts or dreams. You are the awareness in which all of these arise and dissolve.

That awareness is who you really are. That is the message of the Mandukya Upanishad.
