very true choirfeind...
I don't have much regarding prayer rule, since I don't at the moment have a spiritual father (haven't in quite a while, actually, actually, never really have had one, though when I need advise I usually just go to my dad, whose a priest).
However, lately (past 3-4 months) I find myself saying "Gospodi Pomiluy" very often. Even when I'm not even thinking of religion (which is unfortunately often) suddenly "Gospodi Pomiluy" will pop into my head. Sometimes its if I yell at a stupid driver, or sometimes it's at work when I have to deal with a specifically difficult accounting problem.
Most interesting of all, since I am taking courses in Massage Therapy, I've been thinking that at school. Massage is associated with a lot of Yoga and all that cr@p, and when I have to concentrate on providing a client with an excellent (I hope) massage, I find myself chanting "Gospodi Pomiluy" (funeral melody, I think 5th or 6th tone) along with my strokes, rather than paying attention to the New Age stuff they play on the stereo.
