also searched as "om tat sad iti nirdesho brahmanas trividhah smritah"

Translation

Om, Tat, Sat—thus, Brahman is denoted by this threefold expression. In the past, Brahmanas, the Vedas, and sacrifices were ordained in association with these.

Vāṇi's rendering

Om Tat Sat — the threefold name of the eternal. By it, long ago, priests, scriptures, and offerings were ordained.

Commentary

Three syllables, and everything else came after. Krishna does not describe Om Tat Sat as a formula added to worship; he says worship itself — the priests, the chanted books, the fire and the giving — was ordained by it, long ago. The name came first. We usually work the other way: we build the ritual, then hope meaning collects in it. Arjuna is being shown the opposite order. Meaning is not the residue of a well-run ceremony; it is what the ceremony was made from. So when your work feels hollow, do not add more to it. Say the name over it. Let it belong to what made it.

Frequently asked

What does Bhagavad Gita Chapter 17 Verse 23 mean?
It gives the eternal a threefold name — Om, Tat, Sat — and then says something startling: priests, scriptures and offerings were established by that name, not the other way round. The sacred word is not a decoration on ritual. Ritual grew out of it. Krishna is naming the source before he describes what flows from it.
What does om tat sad iti nirdesho brahmanas trividhah smritah mean?
Om, Tat, Sat — thus the eternal is pointed to in three ways, and this is what memory and tradition have held. Om is the sound the whole begins in. Tat turns you toward what no finger can indicate. Sat is what remains real when everything borrowed has fallen away.
Why are Om, Tat and Sat spoken as three names and not one?
Because no single word can hold it. Om is utterance, Tat is distance, Sat is being. Each fails alone and together they circle what they cannot enclose. Krishna is not offering a definition to memorise. He is giving Arjuna three doors into the same room, and any of them opens.
How do I use Om Tat Sat in my own life?
Not as a charm for results. Speak it at the beginning of what you do — the offering, the giving, the difficult discipline — and the act stops being yours to score. You are returning the work to what it came from. The doing stays the same; the ownership quietly changes hands.
