Tat Tvam Asi
Meaning
Thou art That. One of the four Mahavakyas (Great Sayings) of the Upanishads, from the Chandogya Upanishad of the Sama Veda.

Benefits of Tat Tvam Asi
- ·The most frequently taught Mahavakya in Advaita Vedanta, the teacher's gift to the student
- ·Received as an external affirmation from teacher to student, then internalized
- ·Breaks the fundamental illusion of the separate self (jivatman) being other than Brahman
- ·When truly realized, removes all suffering at its root
- ·Pointed to by Swami Vivekananda, Ramana Maharshi, Nisargadatta Maharaj, and all great Advaita teachers
- ·The deepest form of self-knowledge, higher than any devotional practice
How to Chant
- 1.This is a contemplation, not a mechanical chant
- 2.Sit in deep meditation. Ask: Who is the "Thou" (Tvam)? Trace the "I" to its source
- 3.When the individual "I" dissolves in meditation, what remains is "That" (Tat)
- 4.Study the Chandogya Upanishad and the story of Uddalaka and Shvetaketu
- 5.Best practiced under the guidance of a living Advaita teacher
- 6.Combine with "Neti Neti" (not this, not this) to remove false identifications
Best Time
During deep meditation. After studying Upanishads. In the presence of a qualified teacher.
Recommended Count
No counting. This is a direct pointing, not a mantra for repetition. One genuine recognition is worth more than a million mechanical repetitions.
Frequently Asked Questions
Q.What does "Tat Tvam Asi" mean in practice?
In practice, it means: the ultimate reality that you're seeking "out there", God, Brahman, liberation, is not separate from the consciousness with which you're seeking. The seeker and the sought are one. The wave is not separate from the ocean; it IS the ocean expressing itself temporarily as a wave. When a teacher says "Tat Tvam Asi" to a prepared student, it is a direct transmission pointing to the student's own true nature.
