Еврейская мысль к Кохелет 11:10

וְהָסֵ֥ר כַּ֙עַס֙ מִלִּבֶּ֔ךָ וְהַעֲבֵ֥ר רָעָ֖ה מִבְּשָׂרֶ֑ךָ כִּֽי־הַיַּלְד֥וּת וְהַֽשַּׁחֲר֖וּת הָֽבֶל׃

Итак сними с сердца твоего недовольство, и извергни зло твое; Для детства и юности это тщеславие.

Netivot Olam

In the fourth chapter of tractate Nedarim (Nedarim 22a): “Rabbi Shmuel the Son of Nachami said: Rabbi Yochanan said: Anyone who is angry – every type of punishment of Gehinom shall rule over him, as it is written: “Therefore remove vexation from thy heart, And put away evil from thy flesh; For childhood and youth are vanity” (Ecclesiastes 11:10), and ‘evil’ is only Gehinom, as it is written: “The LORD hath made every things for His own purpose, Yea, even the wicked for the day of evil” (Proverbs 16:4).” And the meaning of this is that one who is on fire with rage is essentially Gehinom, because the power and greatness of the strength of Gehinom is connected to the power of fire, and thus it is said in every place [in rabbinic literature] ‘the fire of Gehinom’. And because man has a spiritual soul, when he becomes angry and departs from the order, every type of Gehinom rules over him, because the Gehinom also is a departure from the order of the world; thus every type of Gehinom rules over he who is angry, and thus it is written, ‘And put evil away from thy flesh’. And because his soul that is angry is spiritual, and he departs from the Name May He Be Blessed by way of the anger, thus the Gehinom which is also spiritual and departs from the balance rules over him. [Nedarim 22b continues…] “Rava Bar Rav Huna said anyone who is angry – even the Shechina is not important to him, as it is written (Psalms 10:4), “The wicked, in the pride of his countenance [, saith]: 'He will not require'; All his thoughts are: 'There is no God.'” Rabbi Jeremiah from Difty said: he also forgets his Torah learning and adds stupidity, as it says (Ecclesiastes 7:9), “For anger resteth in the bosom of fools,” and it is written (Proverbs 13:16), “But a fool unfoldeth folly.” Rav Nachman said it is known that [as a result of getting angry] your sins will be greater than your merits, as it says (Proverbs 29:22), “And a wrathful man aboundeth in transgression.” ” And that which is written that the Shechina is not important to him – this is as I will explain, for when a person is angry, he departs from the appropriate order and therefore leaves the order until the Shechina is no longer important to him on a large change, because the person is aligned with the Name May He Be Blessed, who is his Cause, and when he is angry he departs from the order, and thus it says also the Shechina is not important to him because he does not recognize his Cause, may He be blessed, when he departs from the order. And it is said also that he forgets his Torah learning, as it was explained above, because his wisdom is the organization of his intellect, from the angle that he departs from the order and therefore his intellect leaves him. And thus that which is written that he is a sinner is also this idea, for every sinner departs from the fitting path, which the Name May He Be Blessed set for him, and because of this he is a sinner, and this idea is obvious. And these three ideas mentioned here - that the Shechina is not important to him, and that he forgets his Torah learning, and that he becomes a sinner – each one adds to the other: when the Shechina is not important to him, this is the primary root [lit. first] – when therefore he departs from the order until the Shechina is no longer important to him; and more, when his wisdom is removed from him when he does this there is an impression on himself until his wisdom departs from him; and it adds even more that he becomes a sinner himself. And this is also because the anger is a completely foreign departure from the fitting order until he will find these three ideas, which are foreign, and by way of these three he will depart from the order in everything when he understands these three ideas. ...

Duties of the Heart

Among them what is written: "For to the man that is good in His sight He gives wisdom, knowledge, and joy [but to the sinner He has given an occupation to gather and to accumulate]"(Koheles 2:26), and it says: "The heart of the wise is in the house of mourning; but the heart of fools is in the house of merrymaking" (Koheles 7:4).
"It is better to go to the house of mourning, than to go to the house of feasting: [for that is the end of all men; and the living will lay it to heart]" (Koheles 7:2), and it says: "The sleep of a laboring man is sweet, [whether he eats little or much: but the abundance of the rich will not allow him to sleep]" (Koheles 5:11), and "for childhood and youth are vanity" (Koheles 11:10), and "The end of the matter, all having been heard: fear G-d, and keep His commandments; for this is all of man" (Koheles 12:13).
