Thanissaro Bhikkhu "Kindfulness", Meditations6

"You don’t beat yourself up over your mistakes. You try not to make mistakes so that you don’t have the extra burden of looking back on blameworthy mistakes — i.e., ones where you knew better but went ahead with harmful behavior anyhow. But when you do make a mistake, you say, “Okay, that was a mistake. What can I learn from it?” You realize that beating yourself up extra hard is not going to compensate for something you did — and it’s certainly not going to put you in a better position to do it skillfully the next time. The more you look at the events in the mind in this way, the more you see that what you thought were things or entities or inherent natures you couldn’t change are actually actions.
