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.
Learning and wisdom are superfluities, the surface glitter merely, but it is the heart that is the seat of all power. It is not in the brain but in the heart that the Atman, possessed of knowledge, power, and activity, has its seat.
-Swami Vivekananda
