Vivekachudamani is a text by Adi Sankaracharya that provides a complete study of vedanta. It starts with the characteristics of a well-prepared student. It shows us the nature of the Self using the methodology of Atma-Anatma Viveka. It finally takes us to an understanding of the oneness of Atman and Brahman and the characteristics of a Realised Soul.
