Whatever you do or don't do is your contribution to reality. Nothing could be easier. Nothing else is required, you can't do it wrong. The side paths are your judgments about what you are doing or not doing as actions already part of the past. Learn from the past, by all means, but if you feel any guilt or shame about it, you are just inflicting violence on yourself, and violence doesn't work.
-adapted from "A Thousand Name For Joy" by Byron Katie.
