Wisdom is: de-link the event with the emotion, and de-ink the emotion with the sensation. Ignorance is: if you have a some sensation, some sadness, feeling, link it back again to the event. That makes you more miserable, and sets the chain to go on and on, and on.
See how a mistake has happened out of tension. Knowing that a mistake has happened, if you think, It is *my* mistake, then you are not releasing the tension, you are doubling the tension.
