Kabbalah su Proverbi 24:10

Another reason for Keri is the pleasure of sleeping all night, as I said in chapter 5, and this is included in “If his sons forsake My law” (Psalms 89:31). And the reason for this is since he relinquished himself from dealing with Torah the Creator becomes his enemy, as it says “if you are slack in the day of trouble, how small is your strength” (Proverbs 24:10). This is measure for measure, since he did not want to connect with the “God fearing woman” [the Shechinah] via the study of Torah, he in turn connects to the External and foreign woman. He thus will bare demons to prosecute him and he will eat the fruit of his doings, since no evil comes down unless man cleaves to the Other Side, which makes the holiness leave, and then the Chitzonim have control over him since they are always ready and available. They are also called “Eleh” (these), as it says “since I do not have God in my midst these evil things befall me” (Deuteronomy 31:17). Therefore, when he awakes he should hasten to get up, since if he does not wake up and goes back to sleep he might sleep on his back facing up, which is cursed by the Scribes, as it says “Rabbi Yehoshua Ben Levi curses those who sleep on their back facing up” (Tractate Brachot 13b).
