The Upanishads and the Search for the True Self

Two birds in a tree

Who am I? This is perhaps the oldest and deepest question in philosophy. More than two and a half thousand years ago, the sages of the Upanishads rose up to it. Their meditation, often conveyed obliquely in the form of stories, remains one of the most striking and illuminating in the history of human thought.

The Story of Indra

In the Chandogya Upanishad (c. 7th century BCE), Indra, king of the Vedic gods, and his nemesis, Virochana, king of the asuras (anti-gods), go to the ashram of the creator god, Prajapati, to learn the secret of Atman (the Self).

Prajapati takes them both in, and, after 32 years, summons them and tells them that Atman is the reflection of the self in the pupil of the eye. Satisfied with this answer, Virochana returns to the asuras, who take to venerating the bodily self.

But Indra is not so sure, and goes back to the ashram. After 32 more years as a brahmacharya (celibate student), Prajapati tells Indra that Atman is the dream self.

Still full of doubt, Indra is made to wait another 32 years, before being told that Atman is the unconscious self.

When Indra protests that no good can come of this knowledge, Prajapati keeps him for five more years and, after a total of 101 years, finally tells him the secret of Atman.

If Atman is neither the waking self, nor the dreaming self, nor the sleeping self, then what is Atman?

By having Indra wait for what is the natural lifespan of a wise person, Prajapati is making the point that the deepest truths cannot simply be taught, but must painstakingly be learnt. Wisdom is not something that can simply be handed over. It demands patience, perseverance, and, above all, the willingness to question even the answers one has already received. Virochana was content with appearances; Indra sought the truth behind them.

The Upanishads return to this mystery again and again. In one Upanishad, Indra spends a lifetime seeking the Self. In another, the same mystery is pursued by a very different seeker.

The Story of Nachiketa

The brahmin (priest) Vajashravasa purports to be sacrificing everything he owns, but his son Nachiketa notices that he is only offering up those cows that are old, lame, or otherwise unproductive.

Nachiketa repeatedly taunts his father, saying, “I too am yours! To which god will you offer me?” In a fit of rage, Vajashravasa cries out, “To Yama himself!”

Taking his father at his word, Nachiketa descends to Yama’s abode. But the god of death is out, and the boy is made to wait for three days without food or water. When Yama returns, he offers the brahmin boy three boons to atone for his lack of hospitality.

For the first boon, Nachiketa asks for peace between himself and his father when he is returned to the old man. Yama happily grants this.

For the second boon, he asks to learn the fire sacrifice, which he performs to Yama’s satisfaction.

Finally, for the third boon, he asks to be told what comes after death.

Yama replies:

Here, even the gods of yore had doubt. Indeed it is not easy to know—subtle is this matter—O Nachiketa, ask for some other boon. Press not this on me; give this up for me… Ask for centenarian sons and grandsons, many cattle, elephants, gold and horses. Ask for wide extent of earth and live yourself, as many autumns as you like.

But Nachiketa resists the riches of the world, saying that man is not to be satisfied with wealth: “If wealth were wanted, we shall get it, if we only see thee.”

Impressed by the boy, Yama agrees to tell him the Secret of the Self, which persists beyond the death of the body.

After a time, Nachiketa bids farewell to Yama and returns to his father as a jivanmukta, that is, one who has achieved moksha (liberation) in this life.

Whereas Indra’s trial was patience, Nachiketa’s was temptation. Both the god and the boy proved themselves worthy of the knowledge they sought.

The Secret of the Self

One seeker waited 101 years. Another contended with Death himself. Both sought the same truth.

What did Yama tell Nachiketa? And what, in the Chandogya Upanishad, did Prajapati finally tell Indra?

“Atman” is often translated into English as “soul” but does not include the individual or cognitive aspects of the Judeo-Christian soul and, for this reason, is better translated as “Self.”

In Hindu thought, the individual aspects of the Judeo-Christian soul, such as ego, mind, reason, emotion, and desire, are subsumed under the jivanatman (“life-breath”), or jiva for short.

Whereas the jiva, the personal self, is enmeshed in the world, the Atman is detached from this contingent life and incarnation. And whereas the jiva is ever-changing and evolving, the Atman, the universal Self, is steadfast and immoveable.

In the Shvetashvatara Upanishad, the jiva and Atman are compared to two inseparable birds sitting in a tree (the body). One bird, the jiva, gorges on the sweet and bitter fruits of the tree, while the other, tasting of neither, calmly looks on.

The Atman is neither the waking self, nor the dreaming self, nor the sleeping self, as Indra had been led to believe, but pure consciousness, or witness-consciousness, and of a kind with the supreme soul, Paramatman, which is either Brahman or an aspect of Brahman.

There is something within us that witnesses every thought without itself becoming a thought, every emotion without itself becoming an emotion. Our bodies change, our memories fade, our personalities evolve, yet the simple fact of awareness remains. The sages of the Upanishads identified this silent witness with the Atman.

In all living things, Atman is the spark of life, or light of consciousness, that ignites and illumines all else for the time that it remains embodied. It is the eternal core of a living being, which, in death, leaves it for another form, or, at long last, returns to the infinity of Brahman.

If the Self, the Atman, is made of the same stuff as the world, then self-understanding and self-control become means of understanding and controlling the world and existing on a higher plane.

In the Katha Upanishad, Yama tells Nachiketa:

Subtler than the subtle, greater than the great, in the heart of each living being, the Atman reposes. One free from desire, with his mind and the senses composed, sees the glory of the Atman and becomes absolved from grief.

Knowledge of the Self can be attained through the practice of yoga, which Yama defines for Nachiketa as ‘the firm holding back of the senses’.

This is the first recorded mention of ‘yoga’ in something close to its modern sense—and it is put into the mouth of Death himself.

Yama warns Nachiketa to be watchful, ‘for yoga comes and goes.’

More than twenty-five centuries later, the question that drew both Indra and Nachiketa remains our own. We spend much of our lives identifying ourselves with our bodies, our ambitions, our possessions, our memories, even our thoughts. The Upanishads invite us to look deeper. Beneath everything that changes, they suggest, lies something that does not: the silent witness, the Self, which is not merely ours but one with the universe.

Whether one accepts this vision or not, it remains one of humanity’s most beautiful and profound meditations on the oldest of all philosophical questions:

Who am I?

The Uncanny Parallels Between Plato and the Upanishads

Le Char d'Apollon, by Odilon Redon
Know the Self as the rider in the chariot, the body as the chariot itself; know the intellect as the charioteer, and the mind as the reins. —Katha Upanishad

By Dr Neel Burton — Psychiatrist, philosopher, and wine writer; Fellow of Green Templeton College, University of Oxford; author of over twenty books.

Essay substantially revised on 14 August 2026.

Coming to Indian philosophy after having written three books on Greek philosophy, I have been struck by the parallels. And I have been asking myself: are the similarities between Greek and Indian thought the result of direct or indirect communication, or are they the result of a common source or common grammar (Sanskrit being closely related to Greek)? Or are they rather a universal product of the human mind?

The possibility of contact cannot be dismissed. By Plato’s lifetime, the Persian Empire had brought the Greeks and Indians within the same vast political and commercial sphere. Ideas, like goods and people, could travel great distances. But possibility is not proof, and there is no evidence that Plato himself encountered the Upanishads.

Introduction to the Upanishads

‘Upanishad’ means something like ‘hidden connections’, ‘secret teaching’, or ‘esoteric doctrine’, literally, ‘a sitting at (the feet of the teacher)’. Although part of the Vedas, the Upanishads tend to take a dim, if diplomatic, view of what went before. ‘Of what use,’ asks the Svetashvatara Upanishad, ‘is the Rig Veda to one who does not know the Spirit from whom the Rig Veda comes?’ By a strict definition, there are around 108 Upanishads, but the first dozen are the most important.

Like the writings of the pre-Socratic philosophers, some of these mukhya (major) Upanishads are in prose, others are in verse.

Although it is the philosophy and poetry that are retained, the content of the Upanishads is very diverse. The Upanishads fit into the Vedic tradition, and, like older layers of the Vedas, may include mantras, rituals, creation myths, lineages of teachers, historical narratives, and the like. At their best and most original, they take the form of a philosophical dialogue, not unlike those of Plato, with named interlocutors presenting and debating various viewpoints.

For example, in the Great Forest Upanishad (which is the oldest Upanishad, dating from around or before the sixth century BCE), the sage Yajnavalya engages in philosophical debate with, among others, his wife Maitreyi, the sage Gargi (another, rare, woman), and King Janaka of Videha—who salutes Yajnavalya with ‘namaste’. In the Chandogya Upanishad, the sage Uddalaka Aruni—the guru (teacher) of Yajnavalya—engages in debate with his son, Svetaketu.

Yajnavalya, Uddalaka, and Svetaketu are among the first philosophers in recorded history.

Brahman and Atman

This being philosophy, there is a tendency to abstraction, to reach ‘at the truth behind the truth’ (satyasya satyam).

The central vision is one of pantheism (all is God) or panentheism (all is in God), with God hidden in nature ‘even as the silkworm is hidden in the web of silk he made’. God is Brahman and the part or aspect of Brahman that is in us is Atman.

The aim then becomes to achieve the knowledge and unity of Atman and Brahman, which is wisdom, salvation, and liberation (moksha).

These ideas are neatly encapsulated in this passage from the Mundaka Upanishad:

As rivers flowing into the ocean find their final peace and their name and form disappear, even so the wise become free from name and form and enter into the radiance of the Supreme Spirit who is greater than all greatness. In truth who knows God becomes God.

Parallels With Parmenides and Greek Philosophy

The student of Western philosophy might be reminded of the pre-Socratic Parmenides (d. c. 400 BCE), who, in his poem, On Nature, contrasted the way of truth to the way of opinion. Through a chain of strict a priori deductive arguments from premises deemed incontrovertible, Parmenides argued that, despite appearances (the way of Opinion), the universe must consist of a single, undifferentiated, and indivisible unity, which he called ‘the One’.

These verses from the Katha Upanishad could credibly have been penned by Parmenides:

Who sees the many and not the one, wanders on from death to death. Even by the mind this truth is to be learned: there are not many but one. Who sees variety and not unity wanders on from death to death.

To bolster the philosophy of Parmenides, his student and lover Zeno of Elea produced a set of paradoxical arguments, including the famous Achilles and the Tortoise, designed to undermine ordinary assumptions about motion, space, time, and plurality.

Just as Plato (d. 348 BCE) leaned upon Heraclitus and his theory of flux (‘No one ever steps twice into the same river’) for his conception of the sensible or phenomenal world, so he leaned upon Parmenides for his conception of the intelligible or noumenal world, which he rendered as the ideal, immutable realm of the Forms.

Already, Greek and Indian thought appear to be circling around the same fundamental problem: are the change and multiplicity presented to our senses real, or are they merely manifestations of something single, eternal, and unchanging?

Parallels With Plato

Plato’s Phaedo, in which Socrates discusses the immortality of the soul with a pair of Pythagorean philosophers, is essentially an Upanishad in both form and content. The philosopher, says Socrates, who is soon to drink of the hemlock, aims at truth, but his body is constantly deceiving and distracting him:

The body keeps us busy in a thousand ways because of its need for nurture… It fills us with needs, desires, fears, all sorts of illusions and much nonsense…

Absolute justice, absolute beauty, or absolute good cannot be apprehended by the senses but only by pure thought, that is, by the mind or soul. Thus, the philosopher seeks as far as possible to separate the soul from the body. As death is the complete separation of body and soul, the philosopher aims at death and can be said to be almost dead.

This idea of the soul being waylaid by the body is also found in the Maitri Upanishad, which was written at around the same time as the Phaedo:

The human soul rules the body; but the immortal spiritual soul is pure like a drop of water on a lotus leaf. The soul is under the power of the three constituents and conditions of nature and thus it falls into confusion. Because of this confusion the soul cannot become conscious of the God who dwells within and whose power gives us power to work.

In the Meno, Plato argues that learning is really recollection (anamnesis): the soul already possesses knowledge, and philosophical enquiry merely helps it to remember. Socrates demonstrates the point by questioning an uneducated slave boy until he works out a geometrical problem for himself. The truth, it seems, is not simply out there waiting to be discovered, but somehow already within us—a thought that sits remarkably well with the Upanishadic turn inward towards Atman and self-knowledge.

In the Phaedrus, Socrates, having established its immortality, compares the soul to a chariot with a charioteer and two winged horses. Whereas the chariot of a god has two tame horses, that of a mortal has one tame horse and one unruly one, which is the cause of much hardship for the charioteer.

This passage from the Katha Upanishad appears almost to be elucidating Plato’s chariot allegory:

Know the Atman as the Lord of a chariot; and the body as the chariot itself. Know that reason is the charioteer; and the mind indeed is the reins. The horses, they say, are the senses; and their paths are the objects of sense. He who has not right understanding, and whose mind is never steady is not the ruler of his life, like a bad driver with wild horses.

The two allegories are not identical. Plato divides the soul between charioteer and horses, whereas the Katha splits differently. Yet both arrive at the same extraordinary image: human life as an exercise in charioteering, in which the mind must somehow govern forces that threaten to derail us.

The Form of the Good

For more than two millennia, Western philosophers have been poring over Plato’s elusive Form of the Good. Plato himself devised three interconnected allegories (the sun, line, and cave) merely to point at it. But I can tell you what it is in just one word: Brahman.

Both Brahman and the Form of the Good point beyond the changing world of appearances towards an ultimate principle upon which truth and reality depend. Just as Brahman stands behind the multiplicity of the world as its ultimate ground, so the Form of the Good stands beyond the other Forms as the source of their intelligibility.

Plato even has a theory of reincarnation, leading us to suppose that he must, in a previous life, have been a Brahmin.
