For the present let us consider the position of the adepts as they now exist, or, to use the designation more generally employed in India, of "the Ma… - Alfred Percy Sinnett

Preface to the Annotated Edition Since this book was first published in the beginning of 1883, I have come into possession of much additional information bearing on many of the problems dealt with. But I am glad to say that such later teaching only reveals incompleteness in my original conception of the esoteric doctrine, - no material error so far. Indeed I have received from the great Adept himself, from whom I obtained my instruction in the first instance, the assurance that the book as it now stands is a sound and trustworthy statement of the scheme of Nature as understood by the initiates of occult science, which may have to be a good deal developed in the future, if the interest it excites is keen enough to constitute an efficient demand for further teaching of this kind on the part of the world at large, but will never have to be remodelled or apologized for. In view of this assurance it seems best that I should now put forward my later conclusions and additional information in the form of annotations on each branch of the subject, rather than infuse them into the original text, which, under the circumstances, I am reluctant in any way to alter. I have therefore adopted that plan in the present edition.

For the value of these teachings will perhaps be most fully realized when we clearly perceive that they are scientific in their character rather than controversial... Spiritual truths, if they are truths, may evidently be dealt with in a no less scientific spirit than chemical reactions. And no religious feeling, of whatever colour it may be, need be disturbed by the importation into the general stock of knowledge of new discoveries about the constitution and nature of man on the plane of his higher activities.

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.
