Answer: We must constantly think about our common force so it would correspond to the Creator. It has to grow forth from our equal cooperation, where every person bows down his head, joins the group, and raises the friends in his eyes since without them he would not be able to take one step toward the goal. His mind and feeling are born out of unification, and inside the unity, he finds his soul. Thus, aspiring to the center means aspiring to one’s soul.
No one has his own, separate soul. Baal HaSulam writes that only one soul, one common vessel was created. Therefore, without revealing the center of the group, we remain on the “animate” level, outside of the spiritual world, outside of our soul, and exist in the material bodies.
We must constantly form the center of the group. It is a point, like an elevator that rises up the spiritual degrees by the might of the unity of its constituent parts, rising higher and higher, to greater quality, to a greater concentration of our aspirations and desires. This enormous field is the “territory” of our common vessel.
The Creator endowed us with various qualities by means of the breaking, and with the help of intention we focus on the central point.
