Gayatri Mantra

The Gāyatrī Mantra is a highly revered mantra from the Vedas. Like all Vedic mantras, the Gayatri mantra is considered not to have an author, and like all other Vedic mantras, is believed to have been revealed to Brahmarshi Vishvamitra. It is a verse from a sukta of the Rigveda (Mandala 3.62.10). Gāyatrī is the name of the Vedic meter in which the verse is composed. As the verse can be interpreted to invoke Savitr, it is also called the Sāvitrī mantra. Its recitation is traditionally preceded by oṃ and the formula bhūr bhuvaḥ svaḥ, known as the mahāvyāhṛti, or "great (mystical) utterance".

The Gayatri mantra is repeated and cited very widely in Vedic literature and praised in several well-known classical Hindu texts such as the Manusmṛti ("there is nothing greater than the Savitri (Gayatri) Mantra.", Manu II, 83), the Harivamsa, and the Bhagavad Gita. The mantra is an important part of the upanayana ceremony for young males in Hinduism, and has long been recited by dvija men as part of their daily rituals. Modern Hindu reform movements spread the practice of the mantra to include women and all castes and its use is now very widespread.
