This book is based on the notes of weekly lectures given by Swami Yatiswarananda at Ramakrishna Math, Bangalore. The Swami, a Vice-President of the Ramakrishna Order, was an illustrious disciple of Swami Brahmananda. He was a well-known spiritual figure in the Neo-Vedanta movement and did 17 years of pioneering work (1933-1950) in spreading Vedanta in Europe and USA.
My name should not be made prominent. It is my ideas that I want to see realized. The disciples of all the prophets have always inextricably mixed up the ideas of the Master with person, and at last killed the ideas for the person.The disciples of Sri Ramakrishna must guard against doing the same thing. Work for the idea, not the person.
-Swami Vivekananda
