The Occult World (book)
The Occult World, written by A. P. Sinnett, was first published in 1881. It generated great interest in the West, and went through several printings and editions.
According to the Blavatsky Study Center:
In September and October 1880, H.P. Blavatsky and Colonel Henry Olcott visited A. P. Sinnett and his wife Patience at Simla in northern India. The serious interest of Sinnett in the teachings and the work of the Theosophical Society prompted H. P. Blavatsky to establish a contact by correspondence between Sinnett and the two Adepts who were sponsoring the Society, Mahatmas Koot Hoomi and Morya.
From this correspondence Sinnett wrote The Occult World (1881) and Esoteric Buddhism (1883), both of which had an enormous influence in generating public interest in Theosophy. In The Occult World, Sinnett gave lengthy excerpts from his early correspondence with Mahatma KH. Sinnett also related in detail many of the occult phenomena Mme. Blavatsky performed when she was in Simla.[1]
