Answer: First of all, we need to strive toward the center of the group to realize the great rule of the Torah: Love thy neighbor. Otherwise, it will not be the center.
And through this central point, which determines the beginning and ends at the end of correction, through these definitions, I relate to all of reality and the entire world (the 99%). After all, I want to see all of humanity in this central point, and I surely will see it there!
To the extent that I correct myself in the center of the group, in relation to the rest of the world (toward the ninety-nine percent), with all of the positive and negative qualities that I discover in it, with all of the opinions and perceptions already formed inside of me, to that extent, I will see all of humanity in the center of the group, already corrected and ready for my realization. In this way, I will act from the internal part of the world outward.
By these means, I will establish spiritual dissemination. Then, I will see how effectively it helps the world, and how the world is moving forward and changing.
While the external form remains, in the same way, this world is obliged to exist until the very end of correction, until all of this imaginary reality disappears from our perception. That is why we need to apply effort in external dissemination as well.
However, then we will be able to define the right relationship toward the internal and external and distribute our strength. Our evaluations will change.
So, the center of the group is a point toward which we are aiming before everything else, as if we were setting out from all of the worlds of BYA into Malchut of the world of Atzilut, and then from Malchut of the world of Atzilut, wanting to join into ourselves all of the desires of all of reality and raise them ever higher; we discover ever higher qualities called Zeir Anpin, YESHSUT, Bina, and so on. With these new qualities and understanding, we correct and build the Shechina, the collection of all of the souls.
This is because, when addressing it with my uncorrected qualities, it is as if I am building it; I am joining it as a beneficial, active part. The Shechina is rejoicing in the fact that she no longer needs to separate her organ from herself, but can return it and connect it to herself.
