Answer: We should accumulate efforts in the group before the descent comes, to convince the friends that we have to worry about everyone. There should be the spirit of mutual help in the group. This is called the greatness of the goal that is constantly among us in the air.
A group is where you fulfill the goal, a pool of powers, a pool of exertion. You receive the Light that Reforms through the group and the Light that Reforms connects you to the group. Eventually you discover that this network of connections already exists in the group. You discover the right connection in it and according to the equivalence of form you discover the Creator. All this is fulfilled in the group.
In fact, we constantly correct the group or discover its real form. Now we see it the way it is depicted in our corrupt attributes, as it says: “One judges according to his own flaws.” From above, on the Creator’s part, it’s a whole system, an ideal one. We need to attain the same perspective as from Above. We haven’t met by chance and we have been connected from Above into one group: Someone may enter or leave; someone may be near or far. In such a way, above us, we build the spiritual structure, which gradually becomes one desire that was created by the Creator.
The truth is that there is one point left in the desire that was created by the Creator. Everything else, by which this point was blown up, by developing different connections, manners, systems, all this is a result of the Light’s influence on it. The point of the desire itself remains as it was, but the Light that enters it blows it up and fills it with its attributes. This is called Malchut of Ein Sof (Infinity).
