"It is perhaps desirable to state unequivocally that the teachings, however fragmentary and incomplete, contained in these volumes, belong neither to the Hindu, the Zoroastrian, the Chaldean, nor the Egyptian religion, neither to Buddhism, Islam, Judaism nor Christianity exclusively. The Secret Doctrine is the essence of all these. Sprung from it in their origins, the various religious schemes are now made to merge back into their original element, out of which every mystery and dogma has grown, developed, and become materialised. It is more than probable that the book will be regarded by a large section of the public as a romance of the wildest kind; for who has ever even heard of the book of Dzyan?"
