The purpose of creation is to do good to His creatures, to make them similar to Him. Anything less than that is not considered good.
To realize that goal, we have to observe two conditions: On one hand, the creature has to be separate from the Creator, being seemingly a reality of its own. On the other, the creature has to be similar to Him.
How can we combine the two opposites into one? For that purpose the Creator created an attribute of reception that is opposite to Him and then imparted this receiving desire with His own attribute of bestowal. Thus, a creature has two attributes: desire to receive and desire to bestow.
But a person doesn’t know what to wish for. Caught in the middle between the two equal desires, he won’t be able to do anything, to choose any of them. That’s why the Creator always awakens the desire to receive, the primordial, fundamental nature, which separates man from Him. As for the desire to bestow, one should be asking for the Creator to awaken him, to give him strength.
Being on ‘”friendly terms” with desire to receive, a person is at peace with himself, while remaining opposite to the Creator. If he demands that the desire to bestow reigns in him, he prefers to be like the Creator. That’s how we grow, not as a “function” of the two desires, but by constantly preferring an even greater similarity to the Creator. The key for us is not to shift from bestowal as the goal all the way along the path.
Let the Creator constantly stir up the desire to receive. Our work is to “bypass” the Creator, staying ahead of our egoism, and agree with its growth only under the condition that the desire to bestow will prevail.
It turns out that we are in competition with the Creator: He raises Esau in us, and we demand that He raise our Jacob. In the course of that race a person grows and achieves his or her purpose. At the finish line one will achieve a fully-blown desire to enjoy and a full clothing upon it: the attribute of bestowal.
The result of the contest is a victory over the Creator, as it is written: “My sons have defeated me.” And then comes the universal rejoicing described by Baal HaSulam in the parable about the raising of the slave.
