What is the end of correction? Let us say that I need to fix my car to go somewhere. I take it to a shop, and the mechanic fixes it. Once the car is fixed, this means that I have completed the correction. Now, in a fixed car (or, if it is us we are correcting, then with a corrected common soul) we begin our trip upwards.
However, we do not speak about this. We only speak about the way to attain correction. Kabbalists do not say what happens to the corrected soul. They only hint about the things that await us there, but this is an even higher reality, above all the worlds, above the World of Infinity.
