The six systems of Indian Philosophy are:
Samkhya, the ‘enumeration’ school which posits dualism between matter (prakriti) and the self (purusha), both of which are real, though ontologically distinct.
Mimamsa, the tradition of Vedic exegesis which lays down the rules for interpretation of the Vedas and the correct performance of sacrifices (yajna).
Nyaya, the school of logic.
Vaisesika, the atomist school, associated with Nyaya, which assumes the reality of the many; the constituents of existence do not arise from a shared source; rather, each phenomenon is distinct and separate.
