Jiva Goswami
"Bhedabheda" became a main kind of Krishnaite philosophy, which teaches that the individual self is both different and not different from the ultimate reality. It predates the positions of nondualism (namely Vishishtadvaita of Ramanuja) and dualism (Dvaita of Madhvacharya). Among medieval Bhedabheda phinkers are Nimbarkacharya, who founded the "Dvaitadvaita" school), as well as Jiva Goswami, a saint from Gaudiya Vaishnavism, described Krishna theology in terms of "Achintya Bheda Abheda" philosophical school.
