Gayatri Mantra

The Gāyatrī Mantra, also known as the Sāvitrī mantra

The Gāyatrī Mantra, also known as the Sāvitrī mantra, is a highly revered mantra from the Rig Veda (Mandala 3.62.10), dedicated to Savitr, the Sun deity. Gāyatrī is the name of the Vedic meter in which the verse is composed. Its recitation is traditionally preceded by oṃ and the formula bhūr bhuvaḥ svaḥ, known as the mahāvyāhṛti, or "great (mystical) utterance". Vishvamitra is said to have created Gayatri Mantra.

The Gayatri mantra is cited widely in Vedic and post-Vedic texts, such as the mantra listings of the Śrauta liturgy, and classical Hindu texts such as the Bhagavad Gita, Harivamsa, and Manusmṛti. It is the subject of esoteric treatment and explanation in some major Upanishads, and is also praised by the Buddha in the Pali Canon.

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.
