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.
All power is within you. You can do anything and everything. Believe in that. Do not believe that you are weak; do not believe that you are half-crazy lunatics, as most of us do nowadays. Stand up and express the divinity within you.
-Swami Vivekananda
