The Vivekacūḍāmaṇi sets out the Advaita path in some six hundred verses: the qualifications of the seeker, discrimination between the real and the unreal, the sheaths of the self, and liberation in life. Tradition ascribes it to Śaṅkara, though many scholars doubt the attribution. It has been one of the most widely read introductions to Advaita.
