According to Delores Canon, karma comes from allowing other’s actions and behaviors to affect you, so if you want to end the karmic cycle then its time to forgive the action and let him/her be. An action is just an event, it is us who give it deep meaning, thus allowing it to affect us. See it as an event, it becomes easier to forgive. When you have forgiven, the event ceases to tie you down with all the meaning you have attached to it, and you will start to feel lighter. Don’t become involved in someone else’s karmic cycle.
