First of all, do you believe Karma exists and what is your experience with it, have you ever witnessed it in your life and how? Please comment, i am really interested in discussing this topic....

Yes i do believe and i follow allan kardec

Do you believe it because you have read about Karma and it makes sense or because you have witnessed it and have real life proof?
