For, strange as the statement will appear at first sight, modern metaphysics, and to a large extent modern physical science, have been groping for ce… - Alfred Percy Sinnett

An experiment was in progress to ascertain if ordinary culture had attained a stage at which it would appreciate a flood of new thought relating to a science loftier than any dealing exclusively with phenomena perceptible to the physical senses, and in connection with that experiment I was privileged to receive a considerable volume of information relating to the early history of mankind millions of years antedating the range of historical record; also to the concatenation of worlds and the ultimate destinies of our own. Though crude and incomplete, this preliminary sketch of occult science and of the agency through which, though unknown to the multitude, the purpose of creation was being worked out on the physical plane, thrilled the readers of the message all over the civilized world to an extent which gave rise to an organization, the Theosophical Society, which now covers Great Britain, Europe generally, and the United States of America with innumerable branches.

Men of science in former ages worked in secret, and instead of publishing their discoveries, taught them in secret to carefully selected pupils. Their motives for adopting that policy are readily intelligible, even if the merits of the policy may seem still open to discussion. At all events, their teaching has not been forgotten; it has been transmitted by secret initiation to men of our own time, and while its methods and its practical achievements remain secrets in their hands, it is open to any patient and earnest student of the question to satisfy himself that these methods are of supreme efficacy, and these achievements far more admirable than any yet standing to the credit of modern science.

The information contained in the following pages is no collection of inferences deduced from study. I am bringing to my readers knowledge which I have obtained by favour rather than by effort. It will not be found the less valuable on that account; I venture, on the contrary, to declare that it will be found of incalculably greater value, easily as I have obtained it, than any results in a similar direction which I could possibly have procured by ordinary methods of research, even had I possessed, in the highest degree, that which I make no claim to possess at all - Oriental scholarship.
