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.
Say So'ham, So'ham whatever comes. Tell yourself this even in eating, walking, suffering. Tell the mind this incessantly -- that what we see never existed, that there is only I. Flash--the dream will break! Think day and night, this universe is zero, only God is. Have intense desire to get free.
-Swami Vivekananda
