Advaita Vedanta is one of the most influential philosophical schools within Hinduism. The word "advaita" means "not-two" and points to the teaching's central claim: that the ultimate reality, Brahman, is undivided and that the distinction between the self (Atman) and Brahman is fundamentally a misperception, not a real difference.

The tradition was systematized above all by the philosopher Shankara (likely 8th century CE), who built on the Upanishads, the Bhagavad Gita, and the Brahma Sutras. Shankara argued that our ordinary experience of separate selves, things, and world is pervaded by "maya", a kind of cognitive and perceptual obscuring that makes the unity difficult to see.

Core ideas

According to Advaita, the search for liberation (moksha) is not primarily a search for more information, but a shift in insight: to directly recognize that the self that observes is already identical with the undivided ground on which all experience rests. This is often expressed through the phrase "Tat Tvam Asi", "That thou art".

Meditative and contemplative practice, together with study and discernment (viveka), are used to gradually remove mistaken identifications, rather than to build up a new belief.

Historical context

Advaita developed in dialogue and rivalry with other Vedantic schools, such as Vishishtadvaita and Dvaita, which emphasize a more personal relationship between the individual and the divine. The debates between these schools have continued for over a thousand years and still shape Indian philosophy.

During the 19th and 20th centuries, Advaita gained significant influence outside India, partly through thinkers such as Ramakrishna, Vivekananda, and later Ramana Maharshi, contributing to its spread within Western contexts around meditation and the philosophy of consciousness.
