In its precise and beautiful language, and in that of the other writings of the Sage, which are included in this volume, is presented his brilliant synthesis of all that is best in the Upanishads--the reality of Spirit. The image of the supreme Self, stained by the dust of imaginings, dwelling inwardly, endless, evil, comes forth pure, by the stirring power of enlightenment, as the scent of sandalwood comes clear. . . " And thus clearly, in lucidity and grace, comes forth ¿ankarâchârya's instruction to all who have sensed the possibility of a better world, and will have it so. With the stirring power of enlightenment, the cleansing power of truth, he removes the veils from before the eyes of those who will follow him. A textbook of spirituality is perhaps an impossibility, but this book makes a very close approach to it. As it was the work of Gautama the Buddha to "scatter broadcast throughout the world the teachings of India's Golden Days," so it was the work of ¿ankarâchârya to preserve these teachings, to explain them, and to mark them with a spirit and interest which will not die. It was by the reforming and refreshing of the Doctrine instituted by ¿ankarâchârya at a critical time that the Brâhmans were enabled to carry forth the sacred flame of knowledge and spirituality through dark and difficult centuries.
