Just a point of Ref: It's impossible to prove that karma is real, but for the people who believe in it, it can often lead to stronger friendships and happiness. This is because most people who believe in karma will generally do good to receive something good in return.
I am not sure whether I do believe in Karma or not. Generelly speaking I don't. But sometimes pretty strange things are happening I don't find an explanation for. I admit that. I was occasionally left with open mouth and wide opened eyes in the past. Anyhow, I do strongly believe in principles like fairness and correctness, helping out each other and so on, and that people should live together according to these principles. If so, wonderful things will happen. Maybe due to Karma.............
" Your believing or not believing in Karma, has no effect on it's exsistence, nor on it's consequences to you. Just as refusal to believe in the ocean would not prevent you from drowning" ......F.Paul Wilson
I do believe in existence of oceans as well as in the necessity of breathing, what seems to be difficult under water.
