Because of its Mayasakthi it manifests itself as the Jiva and Jagat. Maya means illusion or the divine potency. Resolving the Sakthi into itself, it also remains unmanifest. In the state of liberation, the individual self merges in Brahman, completely losing its identity. The individual soul dissolves into the absolute.
Evidence is available in the scriptures in support of all three systems of philosophy.
Human life itself is a composite of these three systems. In the wakeful state, man moves about and transacts. He is then in the plane of Dvaita. The world he lives in and the persons he contacts are all entities independent of him. Then comes the next state.
