Vasishtha is one of the oldest and revered Vedic rishis or sages, and one of the Saptarishis. Vasishtha is credited as the chief author of Mandala 7 of the Rigveda. Vasishtha and his family are mentioned in Rigvedic verse 10.167.4, other Rigvedic mandalas and in many Vedic texts. His ideas have been influential and he was called the first sage of the Vedanta school of Hindu philosophy by Adi Shankara.

The Saptarshi are the seven seers of ancient India who are extolled in the Vedas, and other Hindu literature such as the Skanda Purana. The Vedic Samhitas never enumerate these rishis by name, although later Vedic texts such as the Brahmanas and Upanisads do so.
