The Vivekachudamani is an introductory treatise within the  Advaita Vedanta tradition of Hinduism, traditionally attributed to  Adi Shankara of the eighth century, though this attribution has been questioned and mostly rejected by scholarship. It is in the form of a poem in the Shardula Vikridita metre, and for many centuries has been celebrated as a prakaraṇa grantha (teaching manual) of Advaita.
