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.
Bless people when they revile you. Think how much good they are doing by helping to stamp out the false ego. Hold fast to the real Self. Think only pure thoughts, and you will accomplish more than a regiment of mere preachers. Out of purity and silence comes the word of power.
-Swami Vivekananda
