Adi Shankaracharya
c. 788–820 CE — India
“Is the individual self ultimately different from the ground of being — or is the sense of separation the only illusion?”
Primary Contribution
Shankaracharya systematized Advaita Vedanta. He introduced Adhyasa (superimposition) as the mechanism of the ego, and Vivartavada (apparent transformation) to explain how multiplicity arises from one undivided reality without actually modifying it.
Key Ideas
- Adhyasa (superimposition): the ego is a false identification of pure awareness with the body-mind
- Vivartavada: the world is an apparent, not actual, modification of the one Brahman
- Neti Neti ('not this, not this'): systematic negation pointing to the unqualifiable Absolute
- Mahavakyas: 'Aham Brahmasmi' (I Am Brahman), 'Tat Tvam Asi' (That Thou Art)
- Turiya: the fourth, stateless awareness underlying waking, dream, and deep sleep

“Brahma satyam jagan mithya, jivo brahmaiva naparah. (Brahman alone is real. The world is appearance. The individual self is none other than Brahman.)”

Legacy & Influence
Shankaracharya's systematization of Advaita Vedanta established the philosophical backbone of the entire Hindu philosophical tradition. His commentaries on the Upanishads, the Bhagavad Gita, and the Brahma Sutras remain the canonical reference works. He founded four sacred monasteries (Mathas) at the four corners of India, ensuring unbroken transmission for over twelve centuries.
