People in the present day will be slow to believe that any knowledge worth considering can be found outside the bright focus of Western culture. Mode… - Alfred Percy Sinnett

There is a school of Philosophy still in existence of which modern culture has lost sight. Glimpses of it are discernible in the ancient philosophies with which all educated men are familiar, but these are hardly more intelligible than fragments of forgotten sculpture,-less so, for we comprehend the human form, and can give imaginary limbs to a torso; but we can give no imaginary meaning to the truth coming down to us from Plato or Pythagoras, pointing, for those who hold the clue to their significance, to the secret knowledge of the ancient world. Side lights, nevertheless, may enable us to decipher such language, and a very rich intellectual reward offers itself to persons who are willing to attempt the investigation. (Introduction)

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.

It will readily be supposed that the chain of worlds to which this earth belongs are not all prepared for a material existence exactly, or even approximately resembling our own. There would be no meaning in an organized chain of worlds which were all alike, and might as well all have been amalgamated into one. In reality the worlds with which we are connected are very unlike each other, not merely in outward conditions, but in that supreme characteristic, the proportion in which spirit and matter are mingled in their constitution. Our own world presents us with conditions in which spirit and matter are on the whole evenly balanced in equilibrium. Let it not be supposed on that account that it is very highly elevated in the scale of perfection. On the contrary, it occupies a very low place in that scale. The worlds that are higher in the scale are those in which spirit largely predominates. There is another world attached to the chain, rather than forming a part of it, in which matter asserts itself even more decisively than on earth, but this may be spoken of later.
