The Hinduism has always been organic and living. The Hindu philosophers thoroughly probed the origin & dynamics of the world.
During medieval period, the Vaishnava philosophers (Shankaracharya, Ramanujacharya, Nimarkacharya, Madhvacharya and Vallabhacharya) propounded the various conceptions on source of origin of the world and its diversity. The schools of thoughts are mainly divided into five. These schools of Vedanta differ only in their conception of the nature of that unity in its relationship with diversity i.e. God (Formless or Formed Brahman) and diversity in world of animate and inanimate.
Non-Duality v/s Duality:
While Sankara’s system looks upon Non-duality as the sublation of diversity, others look upon, Non-duality as the subordination of all duality to the principle of Unity i.e. the Supreme Being. Each school of Vedanta therefore propounds its own notion of the relationship of unity with diversity. But all deny anything independent of Sat-Chit-Ananda.
Important differences of Vaisnava Philosophies:
Jiva (Atman, soul) –
Creation of world –
Samsara (State of Bondage) –
Jnana (Wisdom) –
Goal of life –
