There is only the desire to receive. The Creator created nothing but it. And the desire wants to become like the Creator.
In what could it become like Him? In bestowal. The desire is filled with a sensation of the Creator, and this is called his “soul,” the “Divine part from Above.” The sensation of correspondence, similarity to the Creator that the desire experiences performing actions of bestowal, is called its fulfillment. It is fulfilled by being similar to the Creator. If it needs to receive to do this, it receives, and if it needs to restrict itself to do this, it restricts itself. The action is not important, what is important is to become more and more like Him.
This is the Lights of NRNHY, which fulfill the desire. I enjoy not them themselves but the fact that I adhere to the Creator. That is why fulfillment could be a tiny spark of the Creator, which gives life to our world, and nothing else. Everything is in the realization of the importance of the Giver; this is what fulfills me. The similarity to Him is what I long for, and this is a spiritual fulfillment for me.
Initially, there is only a spark, which emerged as “something out of something,” and a desire, which emerged as “something out of nothing,” such a primary “elementary particle,” and nothing else. And the rest is being “spread out” from the Creator, from His actions.
