The desire to receive that exists below has to be fully covered by the Light of Hassidim, by mutual bestowal. Then the desire (that is, reception) and bestowal will match one another and together will turn into a vessel for the Light.
This means that I haven’t just received a present, but I also know from whom I receive it. The present itself tells me about His love, but in my vessel there is the Light of Hassidim, and so I begin to feel who He actually is and to what extent the attribute of mercy (Hesed) is typical of Him.
I create such “emotional elements” in my desire to receive that reveal the Giver of the present to me, the Creator, in addition to the present itself. This is all the wisdom of Kabbalah: how to reveal in one’s vessel the ability to understand and to feel Him. A special science, a special wisdom, is required here: I receive a “candy,” and by its sweetness I attain His mind and feelings, until I attain His plan.
Otherwise, I would just enjoy the present like a beast. We are all nourished by and live off the Light of Hochma, but it’s by the wisdom of Kabbalah that we begin to know and to attain the Creator. Therefore, the wisdom of Kabbalah is called “the revelation of the Creator to the created being.”
So we should have the desire to receive, and above it the attribute of bestowal, an intention of in order to bestow. The upper Light is revealed according to the right connection between them. There are two sides to it: On one hand, it gives pleasure to the desire to receive and on the other, it enables the desire to perceive where it comes from, meaning from the Creator’s desire to bestow, from His love. Then a person, who receives in order to bestow, feels a state, a phenomenon, called “adhesion.”
