Musar su Salmi 88:6

The whole purpose of man²Compare Ecclesiastes 12:13. is to control his spirit,³Compare Proverbs 16:32, Avot 4:1. to divert it by his will⁴Meaning: to turn it towards his desired outcome in accordance with the Torah’s prescribed good behavior—as against where uncontrolled desire or instinct could lead him. to whatever his situation demands. [In this case, someone has died, so there is a choice] whether to direct the spirit toward sadness, to be embittered by [the dead man’s loss of] His service, blessed be His name, for it has passed⁵I.e., premature death cut off a person’s service of God before its time. -- because “the dead are free” [of the Torah and commandments]⁶b. Shabbat 30a: “Rabbi Yoḥanan says: ‘the dead are free’ (Psalms 88:6)—when a person dies, he becomes free of the Torah and the commandments.” — or to direct one’s spirit toward calming and relaxing the soul, [by regarding this death as a case of] a good man who is on his way to his eternal rest, which is the aspiration of every human being on the face of the earth. This eternal bliss is the fruit of his purpose; “sweet is the sleep of the toiler…”⁷Compare Ecclesiastes 5:11. R. Salanter’s application is that the person is enjoying the fruits of his labor, i.e. his good deeds, in the next world as he sleeps in death.
