Alfred Percy Sinnett's 1883 systematic exposition of the Theosophical doctrine of human evolution, planetary cycles and post-mortem states, presented as the secret core of Buddhism communicated to him through letters from the 'Mahatmas' Koot Hoomi and Morya — the so-called Mahatma Letters that would become foundational to the Theosophical movement. The book sets out the seven principles of the human constitution, the rounds and races of cosmic evolution, and the elaborate architecture that Blavatsky later expanded in The Secret Doctrine.
One of the founding documents of the Theosophical movement and the work that introduced the Mahatma-letter cosmology to a public English-speaking audience before The Secret Doctrine systematised it. Within Theosophy treated as an authoritative early statement; within Buddhist studies, treated by working scholars (Donald Lopez, Stephen Batchelor) as a Western invention that bears almost no relation to historical Buddhist doctrine. The Mahatma letters themselves have been disputed for over a century — Richard Hodgson's 1885 SPR report concluded Blavatsky had fabricated them, while Theosophical defenders have contested that conclusion. The book's historical importance is undisputed; its accuracy as Buddhist exposition is not.

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 favor 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.

Reception
One of the founding documents of the Theosophical movement and the work that introduced the Mahatma-letter cosmology to a public English-speaking audience before The Secret Doctrine systematised it. Within Theosophy treated as an authoritative early statement; within Buddhist studies, treated by working scholars (Donald Lopez, Stephen Batchelor) as a Western invention that bears almost no relation to historical Buddhist doctrine. The Mahatma letters themselves have been litigated for over a century — Richard Hodgson's 1885 SPR report concluded Blavatsky had fabricated them, while Theosophical defenders have contested that conclusion. The book's historical importance is undisputed; its accuracy as Buddhist exposition is not.
Frequently asked
What is Esoteric Buddhism about?
Esoteric Buddhism is Sinnett's systematic exposition of Theosophical doctrine: the seven principles of the human constitution, planetary chains, rounds and races of cosmic evolution, karma, post-mortem states (Devachan and Kama Loca), and Nirvana — presented as the secret inner teaching communicated to Sinnett by the Mahatmas Koot Hoomi and Morya via correspondence.
Is Esoteric Buddhism actually about Buddhism?
Despite the title, the book has little connection to historical Buddhist doctrine. Working scholars (Donald Lopez, Stephen Batchelor) treat it as a Western invention. Sinnett and his editors clarified that "Buddhism" was used to mean the "wisdom doctrine of the Buddhas" rather than the historical religion — a framing rejected by Buddhist studies scholars.
What are the Mahatma Letters?
Letters allegedly written by the Tibetan adepts Koot Hoomi and Morya to Sinnett between 1880 and 1884, forming the doctrinal basis for this book. Their authenticity has been disputed since Richard Hodgson's 1885 SPR report concluded that Blavatsky had fabricated them. Theosophical scholars have contested that conclusion, and the debate has not been resolved.
