Old truisms are often the wisest. The human mind can hardly remain entirely free from bias, and decisive opinions are often formed before a thorough examination of a subject from all its aspects has been made. This is said with reference to the prevailing double mistake (_a_) of limiting Theosophy to Buddhism; and (_b_) of confounding the tenets of the religious philosophy preached by Gautama, the Buddha, with the doctrines broadly outlined in _Esoteric Buddhism_. Any thing more erroneous than this could hardly be imagined. It has enabled our enemies to find an effective weapon against Theosophy, because, as an eminent Pâli scholar very pointedly expressed it, there was in the volume named “neither Esotericism nor Buddhism.” The esoteric truths, presented in Mr. Sinnett’s work, ceased to be esoteric from the moment they were made public; nor did the book contain the religion of Buddha, but simply a few tenets from a hitherto hidden teaching, which are now explained and supplemented by many more in the present volumes. And even the latter, though giving out many fundamental tenets from the SECRET DOCTRINE of the East, raise but a small corner of the dark veil. For no one, not even the greatest living Adept, would be permitted to, or could—even if he would—give out promiscuously to a mocking, unbelieving world that which has been so effectually concealed from it for long æons and ages. _Esoteric Buddhism_ was an excellent work with a very unfortunate title, though it meant no more than does the title of this work, THE SECRET DOCTRINE. It proved unfortunate, because people are always in the habit of judging things by their appearance rather than by their meaning, and because the error has now become so universal, that even most of the Fellows of the Theosophical Society have fallen victims to the same misconception. From the first, however, protests were raised by Brâhmans and others against the title; and, in justice to myself, I must add that _Esoteric Buddhism_ was presented to me as a completed volume, and that I was entirely unaware of the manner in which the author intended to spell the word “Budh‐ism.”
