The Gāyatrī Mantra is a highly revered mantra, based on a Vedic Sanskrit verse from a hymn of the Rigveda (3.62.10), attributed to the rishi (sage) Viśvāmitra. The mantra is named for its vedic gāyatrī metre. As the verse can be interpreted to invoke the deva Savitr, it is often called Sāvitrī. Its recitation is traditionally preceded by oṃ and the formula bhūr bhuvaḥ svaḥ, known as the mahāvyāhṛti(“great utterance”).
The Gayatri Mantra is repeated and cited very widely in vedic literature, and praised in several well-known classical Hindu texts such as Manusmṛti,Harivamsa, and the Bhagavad Gita.
