What information should I consult if I am contemplating becoming a member of the Esoteric School of Theosophy (EST or ES) of whichever theosophical organisation?
First the letter by Koot Hoomi to Annie Besant, received in 1900.
Second the introductions to the Esoteric Instructions, as published in the H.P. Blavatsky Collected Writings.
In order to know all about the path of the disciple, and what H.P. Blavatsky and the Mahatmas wrote about this essential subject see:
What do I have to do to become a member of the E.S.?
I only know something about the Esoteric Section (E.S.) of the Theosophical Society Adyar. Though there will probably be similarities to the Esoteric Sections (if there are any) of other theosophical organisations. In the Netherlands specific information on joining the E.S. is provided to each new member of the T.S. (Theosophical Society Adyar). I am not sure this is done in all countries. But in all cases the basis is clear: become a member of the Theosophical Society first, be active in it, learn as much as you can in it and only then you are in a position to become a member of the E.S. Specific questions should be directed at official representatives of the Theosophical Society or (preferably) officers of the E.S. The undersigned is neither (writing 2004).
In the T.S. Adyar there are at least the following rules:
1) You have to have been a member of the T.S. Adyar for at least two years.
2) Two E.S. members have to be willing to sponsor your aplication for E.S. membership. This means that one has to usually have been an active member of the T.S.
3) You have to apply for membership through the local representative of the E.S. in your country or region. If your region or country does not have a such a representative, application should probably go directly to the International President of the T.S. (Radha Burnier, right now in 2004). She is also the outer head of the E.S.
There are probably other rules, but not being a member of the E.S. myself, I don't know these for sure. At aplication these will be explained.
