“The Occult Word” is the first book published (in 1881) by A. P. Sinnett from the correspondence with the two Tibetan Adepts who were sponsoring the newborn Theosophical Society. Sinnett gives lengthy excerpts from such correspondence and also relates in detail many of the occult phenomena Mme. Blavatsky performed when she was in Simla (West Bengal, India). This book and his next («Esoteric Buddhism”, 1883) had an enormous influence in generating public interest in Theosophy.
