This book is the compilation of classes given by Swami Tyagishananda, an erudite scholar monk of the Ramakrishna Order, during the years 1945-50. The verses are given in Devanagari script followed by English translation and insightful comments. The author quotes (in Sanskrit) extensively from the philosophical schools and commentaries of Shankaracharya, Ramanuja, Madhva, Vallabha, the Vedas, Upanishad, Puranas, as well as from works of western philosophers and scriptures of various other religions. But throughout the text, he interprets his views in accord with the teachings of Sri Ramakrishna and Swami Vivekananda.
Always discriminate -- your body, your house, the people around, and the world are all unreal like a dream. Always think that this body is only an inert instrument. And the Atman within is your real nature.
-Swami Vivekananda
