Answer: The center of the ten is the point from which each of us annuls himself with regard to the other friends. When the whole ten annul themselves with regard to each other, we attain the center. Then the revelation of a wonderful attribute takes place, the attribute of spirituality, and the entrance to the upper world opens up before us.
This is actually a wonder, a miracle, the transition to another dimension that is between us. If each of us fully annuls oneself for the sake of togetherness, the point of togetherness suddenly becomes the gate, the passageway, to the upper world. This is what we have to do, and then everything will be revealed before us.
