Musar for Pesachim 226:9

And you often see people who when they are angry and persist in their wrath, are not conscious of what they are doing and do many things in their anger which they would not do if they were free from anger, for anger draws out the intelligence of a person from within him until his angry deeds multiply and he is plunged into strife and quarrel. Therefore, it is impossible that the wrathful person should be saved from great sins. And so did Elijah say to Rabbi Judah : "Fall not into a passion and you will not sin" (Berakoth 29b). And the Sages said : "By three things is a man known" (Erubin 65b) and one of them is his anger, for when a man is angry his true nature can be recognized. If his wrath is stronger than his wisdom and he does things in the moment of his anger without regard to his wisdom, then you can see the character of his wrath. But if his wisdom is stronger than his anger and he de does not say or do anything when angry that he would not say or do when he is free from anger, then you can see the extent of his wisdom. And the Wise Man said : "Three, the Holy One Blessed be He loves and one of them is he who does not anger" (Pesahim 113b). And our Sages said : "Nor is an impatient person fitted to teach" (Aboth 2:5), for because of his great anger, the pupils fear him too much to ask the things of which they are in doubt lest he be wrathful with them. And even when his pupils do ask the impatient teacher questions he has neither the mind nor the patience to explain to his pupils all that is needed to make the matter clear. Then, too, he will answer questions in anger and thus the pupils will not understand the matter clearly. As for the pupils, it is their duty even when their teacher is angry with them, to ask their questions and listen carefully and not be hurt by the anger of their teacher nor quarrel with him. Concerning such pupils our Sages taught : "So the forcing of wrath bringeth forth strife" (Proverbs 30:33). Any pupil whose teacher is angry with him repeatedly but bears the teacher's wrath in silence will merit to discern between civil and criminal law. And a master said : "There is nothing more difficult than civil and criminal Law" (cf. Berakoth 63b).

HONORING OTHERS: The fourth division is granting honor to every person. Likewise we learned "who is honorable? He who honors the public" (Avot 4:1). They further said: "from where do we know that a person who knows that his neighbor is greater than himself in even one respect must show him honor?..." (Pesachim 113b).

The second thing that can stir the heart to repentance is when old age comes upon a person and he sees the weakening of his strength, then he understands what must ultimately be his fate, and he will remember his end, and he will return to God, and He will have mercy upon him. And he who does not return in repentance at the time of old age, his punishment will be double, as our Sages, of blessed memory, said, "There are four kinds of men that the mind of man cannot bear, and these are they: A poor man who is arrogant, a rich man who deceives, an old man who is lecherous, and a community leader who lords it over the congregation without reason" (Pesahim 113b). And when a man sees that his days are passing, and that his constitution is growing weaker, and that this is the beginning of the journey that he is taking to his Eternal Home, and that he is travelling day and night, it would be a matter of great astonishment if such person did not set his heart upon preparing provisions for his great and distant path. This only happens if he has little faith.
