Likutei Moharan, Part II 49:1/ליקוטי מוהר"ן·תנינא מ״ט:א׳

1Considering God’s greatness and the magnitude of His exaltedness, the slightest motion or glance unbefitting His glory would warrant that a person suffer commensurately, God forbid! God forbid!

2However, God is full of compassion, and the entire world is filled with compassion, and He very much wants the world. Therefore, a person has to give himself great encouragement in his own service of God by every possible means, even if he is as he is. And he should rely on His limitless mercy, because He will surely not abandon him even if he has transgressed as he has. The past is gone, so the main thing is that from here on he does not repeat his actions. At the very least, let him do no wrong, neither in thought nor deed. For the thoughts of such people are also actions, because also in the World of Action there is thought. Thus one has to refrain from acting in deed and thought. And as for what happens to him on its own, let him not be concerned or pay any attention to it.
