Advaita Vedanta is a non-dual school of Hindu philosophy that affirms the fundamental unity of all existence. The term “Advaita” literally means “not two,” indicating that there is ultimately no real separation between the individual self (Atman) and the ultimate reality (Brahman). Brahman is described as the sole, unchanging, eternal reality, often characterized as infinite, formless consciousness. What appears as a world of multiplicity and difference is understood to be an appearance arising through Maya, an illusory perception of separation. This does not necessarily deny the practical functioning of the world, but it denies that this apparent separateness has absolute truth.

At the heart of Advaita Vedanta stands the insight that Atman and Brahman are identical, a vision often encapsulated in the mahavakya “Tat tvam asi” – “That you are.” The individual who takes itself to be a limited body–mind entity is, according to this teaching, misidentifying due to ignorance (Avidya). This ignorance is the root of suffering and bondage, because it obscures the recognition of one’s nature as pure consciousness. When this ignorance is dispelled through true knowledge (Jñāna), there is liberation (Moksha), not as a journey to another place, but as the clear recognition of what has always been the case. Liberation in this sense can be present while living, a state sometimes described as freedom through direct recognition of one’s real identity.

Traditional Advaita Vedanta looks to the Upanishads, the Bhagavad Gita, and the Brahma Sutras as primary scriptural sources, and it often speaks of different levels of reality to clarify experience. On the absolute level (Paramarthika), only Brahman is real; on the empirical level (Vyavaharika), the everyday world of experience operates; and on the merely apparent level (Pratibhasika), dreams and illusions are understood. Within this framework, practices such as study, reflection, meditation, and especially self-inquiry are employed to remove ignorance. Teachers in this lineage emphasize direct recognition of non-dual awareness, encouraging a turning toward the silent, witnessing consciousness that is already free. From this standpoint, Advaita Vedanta is not only a philosophical system but also a radical invitation to see that the seeker and the sought are never two.
