The Framework of Manifestation
Sankhya philosophy offers a framework for all the levels of manifestation, from the subtlest to the grossest. Sankhya comes from samyag akhyate, which literally means "That which explains the whole."
Sankhya deals with prakriti (matter), purusha(consciousness), buddhi or mahat (intelligence), ahamkara (I-am-ness), three gunas (elements of stability, activity, and lightness), mind (manas), cognitive and active senses (indriyas), and the five subtle and gross elements (earth, water, fire, air, and space). In light of its breadth, it contains all of the domains of Vaisheshika, Nyaya, and Mimasa.
