The Ashtavakra Gita (Song of Ashtavakra) is an influential nondualist Hindu text traditionally said to have been written by the Sage Ashtavakra, though its authorship is not known with certainty.

There is little doubt though that it is very old, probably dating back to the days of the classic Vedanta period. The Sanskrit style and the doctrine expressed would seem to warrant this assessment.

The work was known, appreciated and quoted by Ramakrishna and his disciple Vivekananda, as well as by Ramana Maharshi, while Radhakrishnan always refers to it with great respect. Apart from that the work speaks for itself. It presents the traditional teachings of Advaita Vedanta with a clarity and power very rarely matched.
