Therefore, Yom Kippur reveals all our sins that we must gradually correct. From Yom Kippur to Hanukkah, we correct our bestowing desires in order to be only in bestowal, and from Hanukkah to Purim, we also correct the qualities of reception so that they are aimed toward bestowal. Thus, we come to the holiday of Purim.
There are certain prohibitions on Yom Kippur: people do not drink, do not wear leather clothes, and so on. This means that we find egoistic inclusions in all of our desires, and therefore, we cannot use them.
The five types of prohibitions correspond to the five types of restrictions because our egoistic desire consists of five degrees. Each degree corresponds to food, drink, clothing, and so on.
Question: Why is it forbidden to wear leather clothes on this day?
Answer: Clothes (Levush) means that you have a Kli (vessel), a certain correction, and then you can wear such clothes. However, you discover that all of your desires are egoistic, and therefore, you cannot wear them. There is a prohibition on using uncorrected desires.
In his spiritual advancement, a Kabbalist fulfills these prohibitions, meaning restrictions on his desires, checks himself and acts in this way.
Question: Do we also need to observe this in our world?
Answer: Of course, in our world, this exists as a custom. Otherwise, they would not have been passed down from generation to generation for the people and would exist only among Kabbalists who understand their essence and act in this way. Moreover, Kabbalists do this not on the calendar date of Yom Kippur, but every time they are in such a state.
Question: What does a Kabbalist ask for on this day?
Answer: He asks the Creator to help him to exit the boundaries of his egoism. He has no other requests.
There can be only two types of addresses to the Creator: the first is with gratitude for having received such a special work and the second is with a request for strength to rise even higher to the quality of bestowal.
