oṁ tat sad iti nirdeśo brahmaṇas tri-vidhaḥ smṛtaḥ brāhmaṇās tena vedāś ca yajñāś ca vihitāḥ purā
"'Om Tat Sat'—this is the threefold designation of Brahman. By this were ordained the Brahmins, the Vedas, and the sacrifices of old."
What This Means:
Om Tat Sat is the threefold name of Brahman (Ultimate Reality). By this sacred formula, the spiritual traditions—priests, scriptures, and rituals—were established in ancient times.
Going Deeper:
'Oṁ Tat Sat'—the threefold designation (nirdeśa) of Brahman. Om—the sacred syllable representing all. Tat—'That' (transcendent reality). Sat—'Being/Truth' (reality that truly exists). 'Brāhmaṇāḥ, vedāḥ, yajñāḥ'—Brahmins, Vedas, and sacrifices were all 'vihitāḥ'—ordained by this. The formula sanctifies and connects all spiritual practice to Brahman.
How To Apply This:
The mantra 'Om Tat Sat' can sanctify any action. Before important acts, invoking this connects your deed to the ultimate Reality. It's a way of dedicating everything to Brahman.
