Musar su Salmi 69:8

And the highest level in this is that one would be humiliated by all of his iniquities in front of God, may He be blessed. And the content of humiliation is the feeling of shame and change in the radiance of his face, like the matter that is stated (Psalms 59:8), "shame covers my face." And you will see that in every place, humiliation is mentioned after shame - as it is more than shame: "Be ashamed and humiliated" (Ezekiel 36:32); "I am ashamed and humiliated"(Jeremiah 31:19). And when the sinner sees that God, may He be blessed, passes over his transgression, is patient with him, does not pay him back, does not do to him according to His sins and does not pay him back according to his iniquities, he has greater shame in his heart. For does not one who sinned against a king of flesh and blood and was treacherous to him, yet is forgiven by him, feel shame towards him? Accordingly is it written (Ezekiel 16:63), "Thus you shall remember and feel shame, [...] when I have forgiven you for all that you did." And our Rabbis, may their memory be blessed, said (Berakhot 12b) that someone who does something and is ashamed by it has all of his iniquities forgiven. And so do we find with Saul, who said (I Samuel 28:15), "and He no longer answers me, either by prophets or in dreams," but did not mention the Urim and Thumim. For he was ashamed to mention them, since he killed [the inhabitants of] Nov, the city of priests. So Samuel said to him (I Samuel 28:19), "Tomorrow your sons and you will be with me" - with me in my section [of the world to come]." And one acquires the level of shame by meditating to think about the greatness of God, and how evil is the one who rebels against His words; and in always remembering that God sees his deeds, examines his [feelings] and looks into his thoughts.

He who is a true penitent should seek to do good deeds, and to remove himself from thoughts of this world, and to strengthen himself in the counsel of God, Blessed be He, and to take shelter in His shadow, and bear the yoke of the Torah of God, Blessed be He, and bear the revilement of fools, and to be like one who is deaf, blind, and dead against their attacks, as it is said, "Because for thy sake I have borne reproach… I make sackcloth also my garment… but as for me, let my prayer be unto thee, O Lord, in an acceptable time" (Ps. 69:8—14).
