Upadeshasahasri

The Upadeshasahasri, meaning "A Thousand Teachings," is a non-commentative work by the influential philosopher Shankara. It is considered an authentic and excellent introduction to his philosophy. Shankara is most renowned as a proponent of the Advaita Vedanta school of thought, which posits that there is one eternal, unchanging reality, known as Brahman, and that the perceived world of multiplicity is an illusion. The Upadeshasahasri likely explores these core Advaita concepts, emphasizing the nondualistic nature of reality and the path to spiritual liberation through the realization of the identity between the individual self and Brahman.12
