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.
We can never lose what is really ours. Who can lose his being? Who can lose his very existence? If I am good, it is the existence first, and then that becomes colored with the quality of goodness. If I am evil, it is the existence first, and that becomes colored with the quality of badness. That existence is first, last, and always; it is never lost but ever present. - Swami Vivekananda
