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.
Above all, beware of compromises. Hold on to your own principles in weal or woe and never adjust them to others' fads through the greed of getting supporters. Your Atman is the support of the universe -- whose support do you stand in need of?
-Swami Vivekananda
