My Answer: We exist in this process throughout all of history. From one generation to the next, in all our reincarnations, our entire development is meant to bring us to a state where we will be forced to unite. Our whole history began with the breaking of the common soul, our spiritual vessel. From that time on, all these fragments collide with each other, hate each other, and do not understand who they are, where they came from, and why they exist. The most important thing for these fragments is the constant battle between them.
Gradually, step by step, we must come to a thorough understanding that due to our hatred and egoism, we miss out on a lot, in fact, so much so that we must unite. Why? It is because gradually, in the process of our development, we discover that we are connected. We can either kill each other or live together in peace.
However, there is a problem for those who feel an aspiration toward spirituality. The whole world advances toward unity by the path of Beito (in due time). Out of hopelessness, by thinking logically, a person sees that the world must unite. Yet on the other hand, one reveals that we are incapable of it. This is what the whole world feels. Whereas those in whom a point in the heart has awakened begin to hear that we must unite, and that only by uniting can spirituality be reached. However, they do not feel a need for unity. It turns out that some reveal a need to unite, but don’t know how since they have no means for it, while others have the means with the help of which they can unite but lack the inner need for uniting, although the rest of the world has it.
It appears that these two groups, the outer and inner parts, will need to come together and augment each other. We present them with a method of unification, and they give us a need to unite in the same manner that a baby transmits its needs to the parents, and this helps the parents obtain what the baby needs.
Therefore, the external society is the carrier of an inner need for unification, and we are possessors of the method of unification. In this way, we complement each other.
