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.
Work unto death -- I am with you, and when I am gone, my spirit will work with you. This life comes and goes -- wealth, fame, enjoyments are only of a few days. It is better, far better, to die on the field of duty, preaching the truth, than to die like a worldly worm. Advance!
-Swami Vivekananda
