Moshiach: klipa will be purified

In the future it will not only be that the level of Melech haMoshiach will be exalted, but also the enemies will make peace with him. That is to say that the klipa will be purified and will acknowledge the truth, and all the nations will turn around to true belief. "On that day Hashem will be one and His name will be one."

The snake (נחש) will be transformed to choshen (חש"ן) and man will be transformed to a heart that is entirely pure. This is the secret of the existence of Malchus Beis Dovid and Moshiach, who seemingly did not come about in a holy way, G-d forbid. Because Yehuda came to Tamar and he thought she was a zona. And Ruth came to Boaz and revealed his feet, etc., but all of this was from Hashem. Dovid and Moshiach come out in a twisty way, because in the power of this all will be transformed to kedusha in the future and all the external (evil) things will become internal because the Holy One blessed be He will remove from them the evil and all that will remain is the kedusha from their source Above.
