 The classical Indian philosophy of Advaita Vedānta articulates a philosophical position of radical nondualism, a revisionary worldview which it derives from the ancient Upaniṣadic texts. According to Advaita Vedāntins, the Upaniṣads reveal a fundamental principle of nonduality termed “brahman,” which is the reality of all things. Advaitins understand brahman as transcending individuality and empirical plurality. They seek to establish that the essential core of one’s self (ātman) is brahman. The fundamental thrust of Advaita Vedānta is that the ātman is pure non-intentional consciousness. It is one without a second, nondual, infinite existence, and numerically identical with brahman. This effort entails tying a metaphysics of brahman to a philosophy of consciousness.
