Answer: This is a complex system of combined Partzufim, when one’s attainment is partially transmitted to another from the top down or from the bottom up, just as in our world there is a transfer of knowledge between the teacher and the student.
One must have a Kli (vessel) to receive, and the other must have a corresponding desire to give so that a there would be a fusion between them, a proper interconnection, and then from the upper Partzuf, the Light will spread in the measure that you can correctly clothe it in your reflected Light.
Having received from the highest Light in your reflected Light, you can make a Zivug de Hakaa (coupling by striking) on it and correctly receive it.
Remark: But Kabbalists talk about a reality where there are no bodies, there is no time and space—something that cannot be explained.
My Comment: Try to understand creation a little deeper. It consists of a desire and a fulfillment. Clumps of desire and fulfillment—that is the whole reality.
Question: Is it possible to depict all of humanity as one great desire?
Answer: It is so in relation to the Creator, but with respect to us it is a spilled “emulsion,” which must be collected. Imagine that you landed on some planet and there you find something jelly-like and crawling—such is the earthly form of life.
