I also think that charisma and charme have somewhere a common root. Both refer to an elusive property of some person, a property that we cannot pin down exactly, but we that recognize immediately when we see it.
Karma, on the other hand, means as much as fate, as far as I know. In some cultures, karma is more or less something causal, meaning that our deeds in the past lives determine our fate in the current. Maybe Sonu can tell us more about this philosophy :)
