In the early 1880s A.P. Sinnett corresponded with the Mahatmas Koot Hoomi and Morya. In these letters the Masters gave Sinnett the basic ideas of Theosophy on the Occult Constitution of Man; the Planetary Chain; the World Periods; Life after death in Devachan and Kama Loka; the Progress of Humanity; Buddha; Nirvana and the Universe. Mr. Sinnett wrote ESOTERIC BUDDHISM based on his understanding of these teachings. This Theosophical classic was the first simple exposition of Theosophy in modern times.
