Karma? As in the Hindu and Buddhist philosophy according to which the quality of people’s current and future lives is determined by their behavior in this and in previous lives? Hmm... I can't really say yes. But then again I can't say no. Is really hard to say whether it exist or not. I more incline to say yes! Since I consider myself a spiritual person it would be contradictory to refute the posiblity of it's existence.
