We are created from matter which cannot receive Light. Therefore, the only way for us to exist is to enter Bina, the Creator. Bina works on us and raises us up to Her. Her lower part (AHP) descends to us and seems as darkness, which feels undesirable to us. She shines on us with the Light of Bestowal and Mercy (Hassadim), but since we don’t wish to bestow, we perceive it as darkness.
We prepare ourselves to view bestowal as desirable with the help of the Surrounding Light when we work together. Gradually we begin to recognize that there is the Upper One within us. We realize that He is truly the Upper One and we begin to value the quality of bestowal as spiritual. Then, we are prepared to unite with Him and annul ourselves. We are willing to forget about our egoistic desires and attach ourselves to the Upper One like a drop of semen in a mother’s womb.
Then, the Upper One can bring us up; can raise our desires that are ready to adhere to Him. Up where? In the spiritual world is there some other place, higher or lower? No; it is here within us where He begins to cultivate the qualities of bestowal more and more.
This means He is raising us up because we view the quality of bestowal as ascension. Every step we complete results from our more closely uniting with one another and building a system from ourselves that we can present to the Upper One for correction. In this way, we ascend to Bina, and the Light contained in Her expands downward to this world.
Thus, the desires that attach to the Upper One are now not only able to annul themselves, but also to receive and realize the quality of bestowal, to absorb and use it. Obviously, the will remains as receiving, but it changes its intent. So does our world, which is created from the will to receive pleasure; it also begins to gradually receive Effulgence from Above—since the will to bestow appears in it.
