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.
The important thing is how much less you think of the body, of yourself as matter -- as dead, dull, insentient matter; how much more you think of yourself as shining immortal being. The more you think of yourself as spirit, the more eager you will be to be absolutely free from matter, body and senses. This is the intense desire to be free.
-Swami Vivekananda
