Transliteration
om tat sad iti nirdesho brahmanas trividhah smritah brahmanas tena vedash cha yajnash cha vihitah pura
Meaning (English)
The three-fold designation of Brahman is Om Tat Sat. By this the Brahmins, the Vedas, and the sacrifices were ordained in the beginning. From Bhagavad Gita 17.23-28 — the most concise possible affirmation of the supreme reality. Recited as completion mantra at conclusion of every Vedic yajna, ritual, or sacred study. Each syllable carries profound meaning: Om = the cosmic sound, Tat = That which is beyond name and form, Sat = Truth/Being/Reality.
Benefits (Phal)
Universal closing mantra for any spiritual practice. Cultivates the highest Vedantic perspective of non-duality (advaita) — that all distinctions dissolve into the singular reality of Brahman. Daily recitation strengthens equanimity, witness-consciousness, and freedom from petty mental disturbances. Foundational for Jnana Yoga path.
When to Chant
At conclusion of any yajna, ritual, or spiritual practice. Before sleep as final integration. After completing scripture reading. During pranayama practice as breath-anchor mantra.
How to Chant
Sit in meditation posture. Chant slowly with full inhale and exhale — Om on inhale, Tat held, Sat on exhale. Three times minimum. Visualise unity of all phenomena dissolving into one substratum.
