The Samkhya school of philosophy, which follows Prakṛti Parinama-vada (doctrine of the transformation of objective nature), describes the origination and evolution of universe through its theory of Satkāryavāda (Sanskrit: सत्कार्यवाद) which is the theory of causation. According to this theory, the manifested effect is pre-existent in the cause; and the original material cause of everything that is perceived is Prakriti. When Prakriti is not in proximity with immutable Purusha, the conscious ability (chiti-shakti), the three modes (gunas-sattva, rajas and tamas) of prakriti are in equipoise and prakriti is an unmanifest potential. When the conscious ability and the objective ability interact the three modes of the objective nature become disturbed and enter a state of flux giving rise to diverse manifest appearance.
