Musar su Abacuc 1:18

Know that with regard to the repentance which a man does, let him not think that the moment he repents and takes upon himself the obligation that he will not return to his sin, his sin will be forgiven; but only after a length of time in serving God will his repentance be accepted. For the heart is not humbled in one day or two, but in many days. Just as in the case of a king’s son who sins against the king. Even though the king has pity upon him, and intends to do good to him, he will not show him a pleasant countenance except after a long period of affliction and crying out and weeping, just as King David, of blessed memory, did in the case of Absalom. Even though he consented to restore him to Jerusalem, Absalom stood waiting for two years and did not see the face of the king until his heart was completely subdued. Such is the way of the penitent, to plead for many days and to cry out, and then his repentance will be accepted, as it is said, (Psalms 22:3), “O my God, I call by day but Thou answereth not; and at night there is no surcease for me.” And as Habakkuk, the prophet, lamented (1:2), “How long, O Lord, shall I cry and Thou wilt not hear?” Now the prophets are not answered except after much affliction, imploring, crying out, and petitioning, all the more so a man who sins and acts wickedly even in the midst of his affliction. Now, the cause of this is the need to purify the heart, for even though the heart may have a sincere intention, it is necessary to subdue it for many days by intense service to God, by self-affliction, by fasting, and by weeping; then the uncircumcised heart will be humbled. When it is humbled, it will be clean and when it is clean, then the Creator will accept it, as it is said (Job, 13:16), “That a hypocrite cannot come before Him.” And as it is said, (Psalms 24:3), “Who shall ascend into the mountain of the Lord and who shall stand in His holy place? He that hath clean hands and a pure heart.”

The use here of (the word) "eyes" shows that the quality of pride is to be attributed to the sense of sight. Of meekness it is said (Hab. i. 13), "Thou art of humbler eyes than to behold evil," and so forth. With regard to the impudent, thou observest in most cases that his eyes stare and he is indifferent to shame; thus it is said of them (Isa. iii. 9), "The shew of their countenance doth witness against them." Thus thou wilt notice that the eyes of the unrighteous, the impudent, are troubled and restless, like those of whom it is said (Job xi. 20), "The eyes of the wicked shall fail." Again it is said of the impudent (Jer. v. 3), "They have made their faces harder than a rock." On the other hand, thou wilt find that the prudent man lowers his eyes so that he may merit, by reason of this, the abundant favor of God and men, as it is said (Prov. iii. 34), "He giveth grace unto the lowly"; and as we, with the help of God, exalted be He, will explain very clearly in the successive chapters. This favor can be acquired only by means of (the faculty of) sight, having regard to him that sees and that which is seen. Thus it was said of Moses our Master, peace be unto him (Num. xii. 3), "The man Moses was very meek." Previously it was said, corresponding to this (Ex. xi. 3), "The man Moses was very great."

And therefore David said (see Lev. Rabbah 4:8), just as the soul fills the body and carries the body and outlives the body and is unique in the body and does not eat things of the body, sees and is not seen, and is pure within the body and does not sleep, so does the Holy One, Blessed be He, fill His world, as it is said, "Do not I fill heaven and earth? saith the Lord" (Jer. 23:24). And He bears His world, as it is said, "I have made, and I will bear; Yea, I will carry and will deliver" (Is. 46:4). And He outlasts His world as it is said, "They shall perish, but thou shalt endure" (Ps. 102:27). And He is alone and unique in His world, as it is said, "Hear, O Israel, the Lord our God, the Lord is One" (Deut. 6:5). And eating does not apply to Him, as it is said, "Do I eat the flesh of bulls, or drink the blood of goats?" (Ps. 50:13). And He sees and is not seen, as it is said, "Which are the eyes of the Lord, that run to and fro through the whole earth" (Zech. 4:10). And He is pure in His world, as it is said, "Thou that art of eyes too pure to behold evil" (Hab. 1:13). And He does not sleep as it is said, "Behold, He that keepeth Israel doth neither slumber, nor sleep" (Ps. 121:4). Therefore the soul which has within it all these qualities should come and praise the Holy One, Blessed be He, Who has within Himself all these qualities.
