The goal is achieved by building the correct intention over desire.
The right intention is called restriction (Tzimtzum) and Masach. Tzimtzum is a contraction of egoistic desire. And when the egoistic desire is slightly revealed in accordance with the altruistic intention, this is called the Masach. In fact, the screen commands the action.
The idea of creation is that for all the egoistic desires that unfold, one can gradually create a contraction: first, not to use this desire at all, then acquire a Masach, the intention to bestow, and to the extent of this intention, begin to slightly open the desire and add the intention to it.
This is how we receive for the sake of bestowal. This is the meaning of correcting the primordial desire of man—to receive. This is the intention of creation that leads a person to become one with the Creator, to full likeness to Him.
And the further a person advances in mastering the method of correction, the more egoism is revealed in him and the more Masach he must put on his egoism in order to correctly compare the right and left lines and come to the correct work on himself.
