Kumārila Bhaṭṭa (fl. roughly 700) was a Hindu philosopher and a scholar of Mimamsa school of philosophy from early medieval India. He is famous for many of his various theses on Mimamsa, such as Mimamsaslokavarttika. Bhaṭṭa was a staunch believer in the supreme validity of Vedic injunction, a champion of Pūrva-Mīmāṃsā and a confirmed ritualist. The Varttika is mainly written as a subcommentary of Sabara’s commentary on Jaimini’s Purva Mimamsa Sutras.
His philosophy is classified by some scholars as existential realism.
Scholars differ as regards Kumārila Bhaṭṭa’s views on a personal God. For example, Manikka Vachakar believed that Bhaṭṭa promoted a personal God (saguna brahman), which conflicts with the Mīmāṃsā school. In his Varttika, Kumārila Bhaṭṭa goes to great lengths to argue against the theory of a creator God and held that the actions enjoined in the Veda had definite results without an external interference of Deity.
Kumārila is also credited with the logical formulation of the Mimamsic belief that the Vedas are unauthored (apauruṣeyā). In particular, he is known for his attack against medieval Buddhist positions in defense to Vedic rituals. This contributed to the decline of Buddhism in India, because his lifetime coincides with the period in which Buddhism began to decline. His work strongly influenced other schools of Indian philosophy, with the exception that while Mimamsa considers the Upanishads to be subservient to the Vedas, the Vedanta school does not think so.
