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.
We must plunge heart and soul and body into the work. And until we are ready to sacrifice everything else to one Idea and to one alone, we never, never will see the Light.
-Swami Vivekananda
