Jaimini was an ancient Indian scholar who founded the Mimansa school of Hindu philosophy. He is traditionally attributed to be the author of the Mimamsa Sutras text. He is estimated to have lived around the 4th-century BCE. His school is considered non-theistic, but one that emphasized rituals parts of the Vedas as essential to Dharma.
Jaimini's guru was Badarayana, the latter founded the Vedanta school of Hindu philosophy, emphasizing the knowledge parts of the Vedas, and credited with authoring Brahma Sutras. Both Badarayana and Jaimini quoted each other as they analyzed each other's theories, Badarayana emphasizing knowledge while Jaimini emphasizes rituals, sometimes agreeing with each other, sometimes disagreeing, often anti-thesis of the other.
Jaimini's contributions to textual analysis and exegesis influenced other schools of Indian philosophies, and the most studied bhasya (reviews and commentaries) on Jaimini's texts were by scholars named Shabara, Kumarila and Prabhakara.
