Quote by Adi Shankaracharya: “The world is unreal; only Brahman is real; the individual self is Brahman.”

This is the core claim of Advaita Vedanta philosophy. The everyday world of separate objects and people is not ultimate reality — it's a kind of appearance overlaid on one undivided existence. Your deepest self isn't separate from that single reality.

Shankaracharya lived during a period of intense philosophical and religious pluralism in India, when Buddhist and Jain influence was strong and various Hindu schools were competing for intellectual authority. His Advaita synthesis attempted to resolve contradictions within Vedic tradition while simultaneously challenging Buddhist metaphysics on its own terms.

Eighth-century Indian philosopher and theologian who consolidated the Advaita Vedanta school of Hindu philosophy, arguing for a strictly non-dual understanding of reality. He traveled across India establishing monasteries and debating rival schools, and his commentaries on the Upanishads, the Bhagavad Gita, and the Brahma Sutras remain foundational texts in Hindu thought.
