 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.Kumārila is also credited with the logical formulation of the Mimamsic belief that the Vedas are unauthored (apauruṣeyā).In particular, his defence against medieval Buddhist positions on Vedic rituals is noteworthy.
