Nations are like the peel of the fruit

When sin and wrongdoing will be gone from the world, there will be no need for the idol worshipping nations at all...all evil will be eradicated from the nations and nothing will remain of them except for the good parts [righteous of the nations]. Because the nations are like the peel that protects the fruit: it is supposed to benefit the fruit, not harm it.

The klipos have two aspects:

a) the level of klipos that is not evil but is good and it protects the fruit, and this is the secret of Yetzer Hara that betters itself and enters into [kedusha] and this will not be nullified;

b) the evil klipa which is dispicable and causes tzaddikim to stumble and gives rebuke. After the son of the king is no longer in need of rebuke, what do you need the strap for?
