Asato ma sad gamaya

The Pavamana Mantra (pavamāna meaning "being purified, strained", historically a name of Soma), also known as pavamāna abhyāroha (abhyāroha, lit. "ascending", being an Upanishadic technical term for "prayer") is a Hindu mantra introduced in the Bṛhadāraṇyaka Upaniṣad (1.3.28.) The mantra was originally meant to be recited during the introductory praise of the Soma sacrifice by the patron sponsoring the sacrifice.

The text of the mantra reads:

This translates to:

These three statements are referred to as the three Pavamana Mantras.

The word used for immortality here is āmṛtaṃ, and the word used for death is mṛtyor. The word used for light is jyotir, and the word used for darkness is tamas. The word used for truth here is sat (or "sad" in IAST). The word used for falsehood is the negation of sat, asat, a combination of a (negation) and sat.

The Sanskrit term sat, which means "truth" or "what is existing, real", has a range of important religious meanings including "truth" or "the Absolute, Brahman". The passage immediately following the mantra explicitly identifies the unreal and darkness with death and the real and light with immortality, saying that all three portions of the mantra have the same meaning of "Make me immortal." In the interpretation of Swami Krishnananda (1977), "From the nonexistent, from the unreal, from the apparent, lead me to the other side of it, the Existent, the Real, the Noumenon." In keeping with the philosophy of Vedanta, the text rejects the material world as "unreal", "dark" and "dead" and invokes a concept of the transcendental reality (according to this interpretation).
