One point I noticed was that they call him (i.e. he teaches them to call him) "guru". That is, only "guru", without any definite or indefinite article ("guru said this" or "guru did that") (please read the english round letters here (!!): http://www.agpf.de/Chinmoy-Tempel-Heidelberg.htm). That sounds very strange in English and German language, but I think the reason is simple: This makes him more god-like. "God" has also no article in His name. I saw something similar in the Moon cult. They also call the cult leader Moon only "father". Not "the father" or "our father", but simply "father." I think the intention is the same: "Father" is something so special that he does not need an article, he is like God. Cult leaders know very well how to use language to effectively manipulate people.
I think Peter Chang in Bonn does the same when he claims the name "the servant of God." Any humble church leader would use the infedinite article and call himself "a servant of God", only Chang uses the definite article "the servant of God." But I learned that real cult leaders go one step further, they use no article at all. Even as a cult, UBF is only mediocre. UBF is not only a failure as a church, but also as a cult. They are bad copies of Moon, Sri Chinmoy and all the real cult leaders.
