Ramanuja (1017-1137), the great vaishnava saint-philosopher, upheld bhakti (loving surrender to God) as the sole path to the realization of God. His school of philosophy is known as Vishishta-Advaita (qualified monism and his followers, the Srivaishnavas.

He wrote commentaries on the Brahmasutras, the Upanishads and the Bhagwad Gita. It was his view that these three philosophical texts proclaim bhakti as the chief means of realizing God.

In is life and teachings, Ramanuja upheld that all humans are born equal and that caste or social status has no role in determining one’s relationship with God.

For Ramanuja, a Vaisnava (man of God) is worthy of respect; But be defined as true Vaishnava only one who has abundant love for God.
