i can change the past if i can think about it differently in the present.
I’m remembering a conversation. I regret my part in it. My regret has been a source of suffering. I can never get back that opportunity, that particular opportunity to converse with the same people in the same circumstances. BUT… i can vow that in the future, with no mater whom i’m speaking i’ll be more respectful and thoughtful and less disruptive and abrasive. Then i could see that regrettable situation as a great teacher and the beginning of a great reformation in my actions.
With that solace in mind, the past changes from a source of suffering to a springboard of advancement. Seeing the past as a springboard of inner growth is a source of a feeling of fulfilment. In a way, one could say i’ve changed poison into medicine.
In that way, i can change the past.
