Maha Chohan is a compound term meaning "great chohan". It is applied to a certain Adept whose spiritual attainment is superior to that of Masters K. H. and M.. In The Mahatma Letters he is frequently referred as the "boss", "Master" or "chief".H. P. Blavatsky defined it as follows:
Maha Chohan (Sk.). The chief of a spiritual Hierarchy, or of a school of Occultism; the head of the trans-Himalayan mystics.
In a letter to Col. Olcott, Mahatma K. H. referred to the Maha Chohan as he "to whose insight the future lies like an open page". In a letter to Mohini M. Chatterji he said: "One far greater than myself has kindly consented to survey the whole situation".
The Maha Chohan had an active influence in the development of the Theosophical Society. He allowed Mahatma K. H. to correspond with Messrs. A. O. Hume and A. P. Sinnett, and later gave the consent for them to form an Anglo-Indian branch of the Theosophical Society "solely under the express and unalterable condition that the new Society should be founded as a Branch of the Universal Brotherhood".
Mary K. Neff, in her personal copy of LBS, inserted a marginal note: "There was now a new one; the holder of the office had changed." While she does not document this statement, it is underscored by Fritz Kunz near the conclusion of his article "The Ray Key," published in The Theosophist in 1935:
- The Personage who occupied the office of Mahachohan on our globe when the T.S. was first instituted and during its early years has given place to another. . . . The current office holder, in response to the needs of the time, is in appearance ascetic, incisive, and rapid and final in his decisions. The needs of our time, rapid in movement, have evoked him.
