The Zohar, Chapter “Lech Lecha (Go Forth),” Item 6: This is the herald that comes at midnight, at the start of the illumination of the left line from the point of Shuruk for the righteous to raise MAN for extension of the middle line. The herald comes out and calls aloud because it is in the blocking of the Dinim of the point of Shuruk. This is why it is discerned that he comes out with great force and calls upon the righteous to correct him.
Before us is the clarification of the order of extension of the three lines from Bina to ZA, from ZA to Nukva, and from Nukva to the souls of the righteous.
To the extent that the lower one can awaken the Upper One in the middle line by raising MAN (a prayer), the Upper One can fill his desire. We only have to bring our desire to the Upper One, a desire that is similar to His. This means we need to wish to be filled with His fulfillment. Then we will receive it.
There are no special conditions on the part of the Upper One. He is just waiting for our desire to be suitable for His fulfillment according to the law of equivalence of form. This is why all of our prayers and pleas should not be about receiving fulfillment from the Upper One. Rather, they should ask for help to create the correct desire, necessity, and intention, which fit the fulfillment existing in the Upper One.
I am not asking the Upper One to fulfill me since as it said, “more than the calf wants to suckle the cow wants to feed it.” My whole request should be: “I want to become ready to receive from the Upper One, to become fitting for Him.” There must be similar and corresponding properties between us. As soon as it appears, the abundance automatically flows from Him into me.
