The Zohar was revealed only during our times since we have now gone through the inanimate, vegetative, and animate levels of our development and reached the human level (human, "Adam" – from the word "Edame," which means "similar" to the Creator). Therefore, presently we feel a crisis, helplessness, despair, and disappointment in our lives. This is precisely why The Zohar is being revealed: so that we could realize our connection, reach the same system of connection between us as exists in Malchut of Infinity where we are all connected as one whole.
The first stage of correction is called "don’t do to another what you hate." This is the level of Hafetz Hesed (not wanting anything for yourself), the "return from fear (trepidation)." The second stage of correction is even higher; it is the level of "love your neighbor as yourself," the "return from love," receiving for the sake of bestowal. We have yet to perform these two corrections, and they both are realized in the relationships between people.
Then the Creator is revealed in our corrected relationships to the extent that we love and bestow to the neighbor, as it is written: "From love for the neighbor to love for the Creator." Not a single correction can be carried out in any other way except by realizing it in a group of Kabbalists (i.e., those who desire to reach the level of a human being).
In the relationship between them, they build a system of Malchut of Infinity as they wish to feel the Light of Infinity, the Creator, in it. The Zohar needs to provide us with the strength for this, this desire and the inner attainments. Therefore, while we read The Zohar we need to try to be in the intention that we are all one whole that our points in the heart, the desires for the spiritual, unite as one. From these common desires, we build our spiritual vessel, the Shechina, Malchut of Infinity, in which we will feel the Creator.
We need to feel that we are together, like the authors of The Zohar, the group of Rabbi Shimon, and within this system of connection between us, we should try to imagine what this Book is telling us about. After all, the only thing written about in The Zohar is the connection between us. Although this is described in various forms and images that seem to be from this world, it is only the forces of our soul that are described in The Zohar.
