Shankaracharya's Vivekachudamani itself does not need any introduction. It has always occupied the highest position among books dealing with the science of Self-realization and has been the vade mecum for spiritual aspirants throughout the last millennium. Even from a purely literary standpoint, its charm has always been irresistible and captivating. Added to all this, Swami Ranganathananda's commentary on this profound work in the light of modern thought and modern needs is both fascinating and inspiring.
The sages are often ignorant of physical science, because they read the wrong book -- the book within; and the scientists are too often ignorant of religion, because they too read the wrong book -- the book outside.
-Swami Vivekananda
