Swami Yatiswarananda, a Vice-President of the Ramakrishna Order, was noted for the clarity with which he used to explain the nuances of spiritual life. The harmony of the Yogas, the art and science of meditation, the relation between morality and spirituality and such other themes he would illustrate with humorous anecdotes that would leave a permanent impression on the reader's and listener's mind. The book offers encapsulated wisdom.
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
