Be bold and face the truth', said Swami Vivekananda. Here is a book that teaches us how to do it. Here is a book for the guidance of sincere spiritual aspirants who have heard the divine call, who have in response to it accepted God-realization as the highest goal of life, and who consider no sacrifice too great for the attainment of that goal. It is an invaluable guide to practical spiritualiy.
I am the thread that runs through all these pearls, and each pearl is a religion or even a sect thereof. Such are the different pearls, and God is the thread that runs through all of them; most people, however, are entirely unconscious of it.
-Swami Vivekananda
