Ashtavakra is a sage mentioned in Hindu scriptures. He is described as one born with eight different deformities of the body. In Sanskrit, Aṣṭāvakra means "one having eight bends".
He is traditionally regarded as the author of one of the greatest cornerstone works of Advaita Vedanta - the Ashtavakra Gita, a philosophical/metaphysical dialogue between King Janaka of Mithila and Ashtavakra himself.
