Musar sobre Salmos 2:9

The Gemara tells us in Nedarim (10a) that the pious of former times longed for the opportunity to bring sin-offerings. It seems to me that this is because they were in general very strict with themselves, desiring that no blemish should be found in them even through an unintentional sin. Therefore, if they did commit a sin they would rectify it immediately in order not to remain under the dominion of the Sitrah Acharah even for a short time. Thus they would fulfill in themselves the verse, “And do not allow anything of the forbidden things to cling to your hand” (Devarim 13:18). If they were so careful to offer sacrifices for their accidental sins, how much more so must one make amends for intentional transgressions! For Hashem will bring all deeds of judgment. A person might wonder how it is possible for anyone to survive and endure all these judgments and afflictions. But Hashem is merciful and gracious. He does not desire the death of the wicked, only that they turn back from their evil ways and live! This is why repentance preceded the creation of the world (Pesachim 54a) — to teach that were it not for repentance the world could not survive even for a moment. At all four turning points of the year [possibly the solstices and equinoxes] a call to repentance goes forth. Thus we find in the Zohar (Parashas Vayikra 15b): It was taught: At the four turning points of the year, judgments are aroused but repentance can suspend their effects until one makes amends. Just as soon as these judgments are aroused, a proclamation goes forth from one end of the world to the other and the emissaries ascend and then descend again. But the herald makes his announcement and no one is stirred! This is what the Sages were alluding to when they warned that one must be wary of “a drop of blood” at the four turning points of the year. For the “drop of blood” hints at the judgments that are aroused to enter into the world. The remedy for the effects of these turning points is the placing of a piece of iron [on top of all food and drink]. One explanation of this that has found favor in the eyes of God and men is that it is an allusion to the verse, “Shatter them with an iron rod [sheivet barzel]” (Tehillim 2:9).
