being fairly new, I don't know half the rules. I don't feel guilty or worry about it though, if I do something wrong then hopefully the teacher or senior students will tell me, and if they don't...I won't even know I did it wrong, so why worry?
I haven't been to an empowerment yet, I have to admit the idea of blundering does make me a little apprehensive, but I will try to approach it the same way, always just keep my intentions and motivations where they should be, even if my knowledge itself falls short.
"Just as a lotus does not grow out of a well-levelled soil but from the mire, in the same way the awakening mind
is not born in the hearts of disciples in whom the moisture of attachment has dried up. It grows instead in the hearts of ordinary sentient beings who possess in full the fetters of bondage." -Se Chilbu Choki Gyaltsen
