It doesn’t matter what item in or part of The Book of Zohar we study. Rabash used to do this: He would close his eyes, open the book at some page, and begin to read in the middle of the line. He read a few lines, and this was enough for him. And then he would continue to think.
It connects a person to the source that explains to him about the good and correct future state. After all, you don’t know what this source is in itself. You only know that in doing this, you open some faucet that brings you the force, and this force has to influence you. It is as if you open a faucet of water, and it flows on you.
This is the way we need to relate to The Book of Zohar. The “water” flows on condition that we “stand under the faucet.” “To stand under the faucet” means to be together, to yearn as much as possible for unity since this is the nature of the upper waters that pour from one unified vessel. Thus, according to the measure that we unite together, desire to connect, and strive to be as one man with one heart, to that measure the Light of the Torah comes to us, and we merit the reception of the Torah, the reception of the Light.
