The Vivekacūḍāmaṇi of Śaṅkarācārya Bhagavatpāda

"Advaita Vedanta is one of the most important and widely studied schools of thought in Hindu philosophy and the Vivekacudamani is one of the most important texts in the Advaita tradition and the most popular philosophical work ascribed to the great Indian philosopher, Sankara. Sankara (c.650-700) is considered to be a giant among giants and probably the most venerated philosopher in India's long history."--Jacket.
