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.
All that is real in me is God; all that is real in God is I. The gulf between God and me is thus bridged. Thus by knowing God, we find that the kingdom of heaven is within us.
-Swami Vivekananda
