Bharadvaja (भरद्वाज, IAST: Bharadvāja; also spelled Bharadwaja) was one of the revered Vedic sages
(maharishi) in Ancient India. He was a renowned scholar, economist, grammarian and physician. He is one of the Saptarishis (seven great sages or Maharṣis).
His contributions to ancient Indian literature, specifically the Rigveda, provide significant insight into ancient Indian society. He and his family of students were the authors of the sixth book of the Rigveda. In the epic Mahabharata, Bharadvaja was the father of the teacher (guru) Droṇācārya, the instructor to Pandava and Kaurava princes. Bharadwaja is also mentioned in Charaka Samhita, an authoritative ancient Indian medical text.
The word Bharadvaja is a compound Sanskrit from "bhara(d) and vaja(m)", which together mean "bringing about nourishment". the name also lends itself to more than one yoga asana called Bharadvajasana (“nourishing pose”) named after the sage.
His full name in Vedic texts is Bharadvaja Barhaspatya, the last name referring to his father and Vedic deity-sage Brihaspati. His mother was Mamata, wife of Utathya Rishi who was the elder brother of Barhaspati. In the Bhagavata Purana, he is named as Vitatha He is one of the seven rishis mentioned four times in the Rigveda as well as in the Shatapatha Brahmana, thereafter revered in the Mahabharata and the Puranas. In some later Puranic legends, he is stated to be the son of Vedic sage Atri.
In Buddhist Pali canonical texts such as Digha Nikaya, Tevijja Sutta describes a discussion between the Buddha and Vedic scholars of his time. The Buddha names ten rishis, calls them "early sages" and makers of ancient verses that have been collected and chanted in his era, and among those ten rishis is Bharadvaja.
The ancient Hindu medical treatise Charaka Samhita attributes Bharadvaja learning medical sciences from god Indra, after pleading that "poor health was disrupting the ability of human beings from pursuing their spiritual journey", and then Indra provides both the method and specifics of medical knowledge.
