This is a portal into study of The Mahatma Letters to A. P. Sinnett, first published by A. Trevor Barker in 1923. The book was followed by a second edition in 1926, a third edition by Christmas Humphreys and Elsie Benjamin, and a chronological edition by Vic Hao Chin, Jr. This portal is an opportunity for students to view color images of the original letters in a three-column format with transcriptions and notes. Commentaries, background, publication history, and physical descriptions are derived from the work of many ML scholars, including Gottfried de Purucker, Margaret Conger, Mary K. Neff, George Linton, Virginia Hanson, and Joy Mills. Each letter has a name such as "Mahatma Letter No. 1", following the chronological numbering system, but can also be quickly located in Barker numbering, as described in Navigation and shortcuts in the Mahatma Letters Portal.
See About This Wiki for more history of this project. In the future, it may be possible to add images of letters from the Mahatmas to other correspondents, such as those in Letters from the Masters of the Wisdom, and also the letters to A. P. Sinnett from H. P. Blavatsky. Watch for announcements in the Community Portal.
NOTE: As of July 23, 2012, when TS Wiki became accessible on the Internet, an article had been established for each letter. Transcriptions of all letters had been loaded into the wiki, and over half of the 1300 images. Treatment of the question-and-answer letters (such as the Cosmological Notes) has not been finalized. The system administrators will continue loading information into the articles and welcome volunteers to join this effort.
