Vashista (Sanskrit: वसिष्ठ, IAST: Vasiṣṭha) is one of the oldest and most revered Vedic rishis or sages. He is one of the Saptarishis (seven great Rishis) of India.
Vashistha is credited as the chief author of Mandala 7 of the Rigveda. Vashishtha 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 Yoga Vashishtha, Vashishtha Samhita, as well as some versions of the Agni Purana and Vishnu Purana are attributed to him. He is the subject of many stories, such as him being in possession of the divine cow Kamadhenu and Nandini her child, who could grant anything to their owners.
He is famous in Hindu stories for his legendary conflicts with sage Vishvamitra. In the Ramayana, he was the family priest of the Raghu dynasty and teacher of Rama and his brothers.
