Mohini Mohun Chatterji (1858 - 1936) was a Bengali attorney and scholar who belonged to a prominent family that for several generations had mediated between Hindu religious traditions and Christianity.
[3] According to Readers Guide to The Mahatma Letters to A. P. Sinnett, "When HSO opened the first Theosophical Sunday School in Calcutta on March 10, 1883, with 17 boys, Mohini was appointed their teacher".
Mohini worked as private secretary to H. S. Olcott and accompanied him and Madame Blavatsky on their European tour in 1884: The purpose of his trip to Europe was seemingly to give the members there some assistance in understanding the Eastern doctrines which had been brought into prominence by APS in his book Esoteric Buddhism.
Blavatsky to Mr. Sinnett, it would appear that he was going to be used in a similar manner as Babaji was: On February 17th Olcott will probably sail for England on various business, and Mahatma K. H. sends his chela, under the guise of Mohini Mohun Chatterjee, to explain to the London Theosophists of the Secret Section — every or nearly every mooted point and to defend you and your assumptions.
You better show Mohini all the Master's letters of a non-private character — saith the Lord, my Boss — so that by knowing all the subjects upon which he wrote to you he might defend your position the more effectually — which you yourself cannot do, not being a regular chela.
[6]Mohini was present in London in 1884 when the young German artist Hermann Schmiechen painted the Portraits of the Masters.
He was described by Laura Carter Holloway as being “nearer the Master than all others in the room, not even excepting H.P.B.”[7] In 1885, he went to Ireland to lecture, and helped to establish the Dublin Lodge of the TS.
There, he produced a deep impression on Irish poets George Russell (Æ) and William Butler Yeats and is said to have influenced the oriental turn of their writings.
