This great text on Vedanta is attributed to Bhagawan Shankaracharya. Such compositions are called Prakarana Grantha or the book of categories. It deals exhaustively with almost all the aspects of study and practice of Vedanta for the attainment of Self realization. The big volume of the book is due to the poetic and the literary genius that the author was. In addition to the subject matter, many examples conveying the principle and the doctrine of Vedanta make it an essential introductory text for the subsequent study of Prasthana trayee (Gita, Upanishads and Brahma Sutra).
