Most of the time, people pass the buck to their old karma. The tragedy is that in the process, they miss the enormous potential of this moment. They barter away the transformative power of the present by ensuring the future is a repetition of their past. Your old karma is not the problem. The problem is that your present karma is looking for an escape route. It wants to blame someone else. It wants to go to the past, or the future, and escape the present. And so the same old cycle of victimhood and passivity perpetuates itself. Stop and see: you might well find you are doing it right now.
