"What goes around, comes around." "You reap what you sow." "Do unto others as you would have them do unto you." "Don't be an ass." "You brought this upon yourself." Basically, all of those say much the same thing. The way you act and treat others is going to come back to you. Karma, a storytelling game that's up on Indiegogo now, has that same sort of "cosmic balance" thing going on with it.
