Epistemological and Metaphysical Development in Advaita Vedanta

Gaudapada, the grand teacher of Sankara, admits the transcendental reality only. Duality is mere illusion. Gaudapada leads us from gross reality to subtle reality. In meditation also there is a gradual unfolding of subtlety. Sankara deals with both Advaita metaphysics and epistemology. According to him, the source of cognition (pramana is a mental mode (antahkaranavrtti). It removes the ignorance of the object. Brahmakara antahkaranavrtti is the final mental mode. In Advaita epistemology there is a gradual unfolding of mental mode. Sankara advocates three levels of reality- the transcendental reality, empirical reality and apparent reality. All objects, Sankara holds, are real in their own levels of existence. His philosophy teaches us the gradual unfolding of reality.
