Mistakes happen. However more serious than a mistake is not recognizing your error and not letting it purify and mature you.
You need courage to look at yourself; to put you in front of yourself; to face and accept your own shadows, your weak and negatives spots.
This unmasking process is not possible by your strength alone. You need help from another person, from another “you” that consults you.
Recognizing your mistakes aids in the death of the false self so that you can be born to new life.
