As concerns the 24 tattvas, all derivative from the spiritual originant Purusha, they are divided into eight original prakritis (producers), and 16 derivatives of these eight prakritis called vikaras (productions). The eight prakritis themselves spring forth from mulprakriti (original nature or root-substance). In and through these 24 tattvas Purusha manifests itself during the manvantaric period. This system of tattvas therefore is applicable either to the universe or to any entity as a component part of the universe, since the fundamental law of things repeats itself in the great and the small.
The Sankhya school is closely related both in system and philosophical substance to the Yoga school founded by Patanjali.
