Adi Shankaracharya

Overview

Adi Shankaracharya was an Indian philosopher and monk, traditionally dated to the 8th century CE, who is the central historical figure behind Advaita Vedanta — the “non-dual” school of Vedanta philosophy holding that the individual self (atman) and the ultimate reality (Brahman) are, at the deepest level, one and the same. His exact dates are not settled: the dating used on this page (c. 788–820 CE) is the traditional one followed by most of the mathas that trace their founding to him, though a number of modern scholars place his life one to two centuries earlier based on other evidence. What is well documented, across both traditional and scholarly accounts, is the scale of his output and influence: commentaries on the Brahma Sutras, the Bhagavad Gita, and the ten principal Upanishads, a body of devotional hymns still sung today, and four monastic institutions that remain active more than a millennium later.

Life and renunciation

Traditional biographies describe Shankaracharya as born in the village of Kalady in present-day Kerala, and as having shown an early inclination toward renunciation — taking sannyasa (formal monastic vows) as a child, reportedly after a personal crisis persuaded his widowed mother to grant permission. He is described as studying under the teacher Govinda Bhagavatpada, himself a disciple of Gaudapada, an earlier and influential Advaita philosopher. From there, accounts describe extensive travel across the Indian subcontinent, engaging in philosophical debate with teachers of rival schools — Buddhist, Mimamsa, Samkhya, and others — and establishing Advaita Vedanta as a major systematic school in the process. Most traditional accounts describe him as dying young, in his early thirties.

Advaita Vedanta and major works

Shankaracharya’s philosophical project centered on establishing Advaita (“non-dualism”) through close commentary (bhashya) on Vedanta’s three foundational texts — the Upanishads, the Bhagavad Gita, and the Brahma Sutras, together known as the Prasthanatrayi. His Brahma Sutra Bhashya remains one of the most studied works in Vedanta philosophy, and his Upanishad commentaries are still used as a starting point for traditional study of those texts. Beyond formal philosophy, he is also credited with more accessible teaching poems — Vivekachudamani (“Crest Jewel of Discrimination”) and Bhaja Govindam among them — and with a body of devotional hymns, including the Shivanandalahari (“Wave of Bliss of Shiva”), addressed to Shiva.

The four mathas

Shankaracharya is traditionally credited with establishing four mathas (monastic seats), one in each cardinal direction of the subcontinent — Sringeri in the south, Dwarka in the west, Puri in the east, and Jyotirmath (near Badrinath) in the north — each entrusted with one of the four Vedas. These are known as the Amnaya Peethams, and each has maintained an unbroken line of successive teachers who take the title Shankaracharya on assuming the seat, distinct from the historical founder of the same name. Some traditions recognize a fifth matha, at Kanchipuram; this is not universally accepted across all lineages, and this page does not take a position on which reckoning is correct.

Legacy

Adi Shankaracharya’s influence on later Hindu philosophy, monasticism, and devotional practice is difficult to overstate: Advaita Vedanta remains one of the most widely taught schools of Vedanta today, his hymns are still recited in worship, and the mathas he founded continue to train monks and issue religious guidance under his name. Within the tradition, this influence is often described in terms well beyond that of an ordinary philosopher — some devotional accounts hold him to be an incarnation of Shiva. That is presented here as the devotional understanding held within parts of his own tradition, not as a claim this page makes independently.
