Musar su Salmi 51:19

The fourth principle is pain in [his] actions, as it is stated (Joel 2:12), "'Yet even now' - says the Lord - 'Turn back to Me with all your hearts, and with fasting, weeping, and lamenting." And they, may their memory be blessed, said (Yerushalmi Berakhot 1:4), "The heart and the eyes are the two intermediaries of sin." And so is it written (Numbers 15:39), "and you shall not go astray after your hearts and after your eyes." Hence with this will the sin of the intermediaries be atoned - with the measure of repentance according to the measure of the affliction. For the iniquity of the heart is atoned by its bitterness and sighing - with the brokenness with which it is broken, as it is stated (Isaiah 57:16), "when spirits in front of Me cover themselves." And it is [also] written (Psalms 51:19), "God, You will not despise a contrite and crushed heart." And the parable about this is from the [impure] vessels - when they are broken, they are purified, as it is stated (Leviticus 11:35), "an oven or stove shall be smashed." And the iniquity of the eyes is atoned by tears, as it is stated (Psalms 119:136), "My eyes shed streams of water, because they do not obey Your Torah ." It does not state, "because I do not obey Your Torah," but rather states, "they do not obey"; since they were what caused the sin - therefore, I shed streams of waters.

And the seventh principle is whole-hearted submission and lowliness. For the one who knows his Creator knows how one who transgresses His words is crooked and lowly - so he is lowered in his worth, like the matter that is stated (Psalms 15:4), "for whom a contemptible man is abhorrent." And it is [also] stated, (Job 15:16), "What then of one loathsome and foul man, who drinks wrongdoing like water"; [and] (Jeremiah 6:30), "They are called rejected silver." Therefore he will be submissive and lowly in his [own] eyes. And when King David, peace be upon him, confessed after Nathan the prophet came to him, he said at the end of his words (Psalms 51:19), "True sacrifice to God is a contrite spirit; God, You will not despise a contrite and crushed heart" - "a contrite spirit" is a lowly spirit. From this we have learned that submission is from the principles of repentance, since this psalm is wholly founded upon the principles of repentance. And with submission, a man is acceptable to God, as it is stated (Isaiah 66:2), "To the poor and brokenhearted." And it is stated about the matter of repentance, (Isaiah 57:14-15), "[The Lord] says, 'Build up, build up a highway, etc.' For thus said He who high aloft forever dwells, whose name is holy, 'I dwell on high, in holiness; yet with the contrite and the lowly in spirit - reviving the spirits of the lowly, reviving the hearts of the contrite." We learn [also from here] that submission is from the principles of repentance. And likewise does the entire remainder of this section speak about penitents: "For I will not always contend, etc. For their sinful greed I was angry, etc. I see their ways, and I will heal them and I will guide them, etc." (Isaiah 57:16-18). Its explanation is, I see that their ways are [grounded] in submission, as it stated, "yet with the contrite and the lowly in spirit"; and with bitter-heartedness, as it stated (Isaiah 57:16), "when spirits in front of Me cover themselves"; "and I will heal them," as I will forgive his iniquity, like [in] (Hosea 14:5), "I will heal their affliction," [and in] (Isaiah 6:10), "and repent and save itself"; "and I will guide them" - I will help him to leave the sin, and give him strength against his impulse.

And you will also find [another] big and great benefit in breaking desire: For he will reveal his true heart and goodly desire for repentance. As he is disgusted by the nature that caused him to sin. And through this, he will become acceptable to God, may He be blessed, and find favor in His eyes. And it is accordingly written (Psalms 51:19), "True sacrifice to God is a contrite spirit; God, You will not despise a contrite and crushed heart." The contrite spirit is a lowly and submissive spirit; and a broken heart is [speaking] about the breaking of physical desire - for desire is placed into the heart, as it is stated (Psalms 21:3), "You have granted him the desire of his heart." And this verse (51:19) is stated in the psalm of repentance. And from its stating, "You will not despise a contrite and crushed heart," we learn that a penitent becomes acceptable to God, through the breaking of his physical desire, and that this is from the principles of repentance. And it is also stated about the matter of repentance (Isaiah 57:15), "reviving the spirits of the lowly, reviving the hearts of the contrite."
