A common practice in Christianity that long predates the use of the word Amen at the end of prayers (This is funny since its so obvious so few think to notice this blatant rip off) Amen is a name for an egyptian god and was also stolen from the Chant Amon that Egyptians used in worship to Amon Ra the sun god and is also used to open the heart chakra to this day. May I note though that some Christians actually know this though and don’t use it for this reason.
