poorva mimansa is atheistic poorva mimansa is more atheistic than both buddhism and jainism let us see jainism do not entertains concept of god and buddha remained his silence both for god and deities later buddhist rejected god but not deities jainism do believes in deities but in jainism these deities are not siddhas and can only bestow material gains in mahayana even god can be believed and in hinyana and even in therveda deities are not rejected although here not much importance is given that in buddhism deities are symbolic is modern interpretations or propaganda a more traditional buddhist believes in the ontological existence of deities although deities are not so important in dhamma in poorva mimansa the earliest document we have is sabara bhasya a commentary on mimansa sutra attributed to rishi jaimini here only the ontological existence of deities is refuted when sabara writes 'the vedic gods are mere words and sounds ' and 'there existence is not outside of vedas ' no modern propaganda no atheistic interpretations done as done to adwaita vedanta but the earliest resources itself is clear on its starke athiesm later mimansak remains doubtful over deities and mimansak like kumarila and prabhakara wrote extensively to refute the concept of god but maintained silence over deities in a nutshell mimansa was more atheistic in origin over buddhism and jainism today vedanta is more famous among vedics and i too find adwaita if i leave buddhism and jainism more interesting than mimansa not that mimansa is lesser than any other that no no
