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.
Not even the deepest sleep will give you such a rest as meditation can. The mind goes on jumping even in deepest sleep. Just those few moments in meditation your brain has almost stopped. ... You forget the body. ... You feel such pleasure in it. You become so light. This perfect rest we will get in meditation.
-Swami Vivekananda
