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.
Understanding human nature is the highest knowledge, and only by knowing it can we know God. It is also a fact that the knowledge of God is the highest knowledge, and only by knowing God can we understand human nature.
-Swami Vivekananda
