Advaitic Mysticism of Sankara

Brahman, according to the Upanishads and Sankara, the major exponent of the philosophy of the Upanishads known as Advaita, is not a metaphysical postulate meant to explain what is empirically experienced or the word. Brahman is absolutely real and is the inner reality or essence or self of all that is there, including one’s self. Therefore it is known directly and immediately as the real or true nature of one’s self.
