Rabbi Shimon’s Group Comprised of Several Million Members
The upper Light is in a place called "Shechina," which is the unification between the souls. With our efforts we have to attain unity among us. Then we will reveal the Light that builds, creates, corrects, and fulfills all of creation.
This Light is always present in the Shechina, in the assembly of souls that aspire to the Creator (Knesset Israel), in the unification among us.
The Zohar is the same source of Light, but on the condition that we imagine ourselves (and it doesn't matter how many millions of us there are) as being the group of Rabbi Shimon, which had ten people who sat, connected together, and received this Light called "Zohar"-"the upper illumination." This is the Light that influences us, corrects us, and elevates us.
