Ramanuja's Vishishtadvaita school and Shankara's Advaita school are both nondualistic Vedānta schools, both are premised on the assumption that all souls can hope for and achieve the state of blissful liberation; in contrast, Madhvāchārya believed that some souls are eternally doomed and damned. Shankara's theory posits that only Brahman and causes are metaphysical unchanging reality, while the empirical world (Maya) and observed effects are changing, illusive and of relative existence. Spiritual liberation to Shankara is the full comprehension and realization of oneness of one's unchanging Ātman (soul) as the same as Ātman in everyone else as well as being identical to the nirguna Brahman. In contrast, Ramanuja's theory posits both Brahman and the world of matter are two different absolutes, both metaphysically real, neither should be called false or illusive, and saguna Brahman with attributes is also real. God, like man, states Ramanuja, has both soul and body, and all of the world of matter is the glory of God's body. The path to Brahman (Vishnu), asserted Ramanuja, is devotion to godliness and constant remembrance of the beauty and love of personal god (saguna Brahman, Vishnu), one which ultimately leads one to the oneness with nirguna Brahman.
