Answer: That’s exactly what we must discover. In other words, there exists a cause to everything that you could possibly imagine, and this cause is a single, sole source.
This cause arranges, decides, accomplishes, and functions in everything, and it is called “There is none else besides Him.” Who is He?—the force of bestowal and love. Those are His qualities with respect to us. Aside from that, we know nothing about Him.
Question: How am I supposed to work with that?
Answer: You need to constantly reveal Him in every situation, in every action, intention, and thought—in everything—with the understanding that there is a single cause to everything. After all, our nature is matter, the desire to receive, and what brings it into action in all its forms is that same single force besides which nothing else exists.
Why does this force animate matter? Because it wants to push the material world toward unity. Why? It prepared for matter the ability to attain that same single force that is the cause of everything, but the matter has to attain the state of unity first.
And then this matter, to the extent to which it is connected in spite of its resistance, attains “There is none else besides Him,” this single force, and while attaining it, experiences itself existing and in control.
Moreover, above its own experience of existence, it also attains what it means to exist and be in control of all of reality, since that same reason, “There is none else besides Him,” gives this matter, this creation, the ability to be on His level, on the level of the Creator. And then the entire world, the entire created desire to receive, is in control of that same desire and not under the control of the Creator. That is what is meant by perfection.
