Greetings and good wishes, Sergo. I always enjoy your interesting posts.
In a private message to me you asked me something like "what aspect of theosophy [sic. Theosophy] interests you most?" Previously, you had also mentioned that you were a Russian-English language translator. The thought came to me, "Why not try to 'kill two birds with one stone' [a good-old folksy English idiom] and not only begin to answer [the shortest version would be 'Psychological Religion'] Sergo's question, but also give him a nice, advanced challenge for his translating abilities?"
Thus the material below:
Theosophy: “An epistemological term referring to Intuitive knowledge or wisdom resulting from personal experience of one’s own Transcendental (‘Divine’) Nature.”
Psychological Religion*: “Practical, result-oriented applications of Theosophical knowledge or wisdom, including the use of ancient psychological understandings (which may be analogically associated with, and perhaps provide the microcosmic basis for, grand Macrocosmic formulations like karma and reincarnation) in order to personally advance in the (possibly Translifetime) Hierarchy of Self-Awareness.”
*c.f., F. Max Muller’s 1911 book title THEOSOPHY OR PSYCHOLOGICAL RELIGION
All the best, friend Sergo
