Vedanta makes one of the boldest claims in all of philosophy: that the self you take yourself to be is not what you actually are.

There is an ancient phrase from the Upanishads, the foundational texts of Indian philosophy, that contains one of the most audacious claims ever made about the nature of reality: Tat Tvam Asi, usually translated as Thou art That. It is short, and easy to pass over, and almost impossibly large in its implication. It says, in essence, that the deepest reality of the universe and the deepest reality of you are one and the same. That what you most fundamentally are is not the small, separate, anxious self you take yourself to be, but something infinitely vaster, the very ground of being itself. This is the heart of Advaita Vedanta, the school of non-duality, and whether or not one ultimately accepts it, it is among the most profound inquiries into the self that humanity has ever undertaken.

To understand the claim, you have to see the distinction it draws between two senses of self. There is the self you ordinarily mean when you say I: your personality, your body, your thoughts and memories, your roles and history, the particular person you take yourself to be. Vedanta calls this, roughly, the apparent or empirical self, and it is not denied, but it is held to be not your deepest nature. Beneath it, Vedanta points to the Atman, the true Self, which is not your personality at all but the pure awareness in which your personality appears, the silent consciousness that is witnessing these very words, that was there in childhood and is there now, unchanged beneath all the changing contents of your life. And the astonishing claim of non-duality is that this Atman, this innermost awareness, is identical with Brahman, the ultimate reality underlying the entire universe. The deepest you and the deepest reality are not two. That is what Tat Tvam Asi means.
