Zirkoff, Boris

Ramanuja (also Râmânujâchârya and Yatirâja). Hindu philosopher and commentator, fl. in eleventh or twelfth century A.D., at Kanchipuram and Srirangam, near Trichinopoli. Vaishnava reformer. Wrote commentaries on the Brahma-Sutras and the Bhagavad-Gita, and other independent Vedantic treatises. His Vedântism is partly a reaction against the extreme adwaita (monism) of Samkarâchârya, and is known as Visishtâdwaita (qualified monism).
