Answer: It is the result of our mutual incorporation. I am in a corrected world, but at the same time I am connected to all the people in the world and I feel that it is corrupted. This is the difference between private Providence and general Providence: from my attainment to the attainment of everyone else. This state remains until the end of correction.
I saw my teacher, who was a great Kabbalist, on the highest spiritual levels in GAR of Atzilut and at the same time he was ill and needed basic necessities like everyone else. He behaved like any ordinary human being in his corporeal life. If it weren’t so, we wouldn’t be able to connect through our perception of the world.
A Kabbalist perceives the whole world as corrected, but since we are incorporated in it, he sees things that are corrupt. From his subjective perspective he should see all of us at the end of correction, but he sees and perceives us just the way we see ourselves, Baal HaSulam even asked to be lowered even more so he would be able to connect to people.
We cannot understand this split in the perception of reality. It is impossible for us. These are two different levels. The world will be seen through the individual shattered souls until every soul is incorporated in all the other souls. Until then the perspective of the world through the shattered souls will remain even though I may be perfectly corrected. I will still see the world the way my generation sees it by being incorporated in the other souls. At the same time I can be incorporated in all the other generations and see the world through their eyes.
A Kabbalist’s private correction all the way to the actual general end of correction doesn’t free him from being connected to the shattered souls. He also sees what they see and has two forms of reality, both on the level of Bina and on the level of Malchut.
