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.
Take up one idea. Make that one idea your life -- think of it, dream of it, live on that idea. Let the brain, muscles, nerves, every part of your body, be full of that idea, and just leave every other idea alone. This is the way to success, and this is the way great spiritual giants are produced. Others are mere talking machines.
-Swami Vivekananda
