It is not important where we begin to read The Zohar from, what item, or what part of it. Even if a person listens to the lesson for the first time, it is absolutely unimportant. “There is no time in spirituality”; the Torah speaks of spiritual states, all of which occur within us, but we do not perceive it yet.
It is completely irrelevant, though. We need to awaken the Light inside The Book of Zohar, the most exalted, true, and powerful source. No book even comes near to The Book of Zohar‘s influence on the soul.
The only way to draw its Light upon us, for it to have an effect on us, is by obtaining qualities similar to it. Therefore, we are reading The Book of Zohar together. In other words, each of us has to prepare himself to be in connection with the others from the beginning, even before we open The Book of Zohar.
This is what is said about the giving of the Torah: If you agree (obviously, that we cannot do it, but we agree nonetheless) to become “as one man in one heart,” to achieve brotherly love (in the future), then you will receive the Torah, meaning the method of correction by way of the Light that Reforms. Then, that Light will return you to the Source, to the good, to equivalence with the Creator.
That is why when we are reading The Zohar, we have to always strive to meet this condition: Be ready to unite so that the Light will influence us, unite us, and we will reveal the Creator in our unity as in one common soul. An individual soul, after all, can only feel our present reality, the one that we are currently perceiving.
