A special feature of the book is that the learned Swamiji quotes copiously from various Srutis, Smritis and Puranas as also from different orthodox commentators to explore the real meaning of the Mantras of the Ishopanishad.
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
