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.
They alone live whose lives are in the whole universe, and the more we concentrate our lives on limited things, the faster we go towards death. Those moments alone we live when our lives are in the universe, in others; and living this little life is death, simply death, and that is why the fear of death comes.
-Swami Vivekananda
