[3][4] In Samkhya and Yoga, two of the six orthodox (āstika) schools of Hindu philosophy, "there are two irreducible, innate and independent realities: 1) consciousness itself (Purusha), and 2) primordial materiality (Prakriti)".
[citation needed] The unconscious primordial materiality, Prakriti, contains 23 components including intellect (buddhi, mahat), ego (ahamkara) and mind (manas).
Because in Samkhya Yoga mind is an evolute of matter, mental events are granted causal efficacy and are therefore able to initiate bodily motions.
[8] The Dvaita Vedanta school of Indian philosophy espouses a dualism between God and the universe by theorizing the existence of two separate realities.
The distinguishing factor of this philosophy as opposed to Advaita Vedanta (monistic conclusion of Vedas) is that God takes on a personal role and is seen as a real eternal entity that observes itself as the universe.
