Gayatri Mantra
The Gāyatrī Mantra (Sanskrit pronunciation: [ɡaː.jɐ.triː.mɐn.trɐ.]), also known as the Sāvitrī Mantra (Sanskrit pronunciation: [saː.vi.triː.mɐn.trɐ.]), is a sacred mantra from the Ṛig Veda (Mandala 3.62.10), dedicated to the Vedic deity Savitr. The mantra is attributed to the rajarshi Vishvamitra.
The term Gāyatrī may also refer to a type of mantra which follows the same Vedic metre as the original Gāyatrī Mantra (without the first line). There are many such Gāyatrīs for various gods and goddesses. Furthermore, Gāyatrī is the name of the Goddess of the mantra and the meter.
The Gayatri mantra is cited widely in Hindu texts, such as the mantra listings of the Śrauta liturgy, and classical Hindu texts such as the Bhagavad Gita, Harivamsa, and Manusmṛti. The mantra and its associated metric form was known by the Buddha. The mantra is an important part of the initiation ceremony. Modern Hindu reform movements spread the practice of the mantra to everyone and its use is now very widespread.
