This book draws parallels between Sri Ramakrishna's teachings and the words of the scriptures. It thus serves as a commentary on the Master's teachings and helps us to understand them better.
Those who work at a thing heart and soul not only achieve success in it but through their absorption in that they also realize the supreme truth -- Brahman. Those who work at a thing with their whole heart receive help from God.
-Swami Vivekananda
