“Introduction of The Book of Zohar,” Article “Rabbi Shimon’s Exit from the Cave,” Item 186: And that light stands from the heaven to the earth and illuminates the entire world until Atik Yomin, meaning Keter, arrives and properly sits on the throne, meaning until the end of correction. And that light is entirely included in your home, meaning in his daughter, since the daughter of Rabbi Pinhas was the wife of Rabbi Shimon Bar Yochai, and from the light that was included in your home, a small and thin light comes out, which is Rabbi Elazar, his daughter’s son. He comes out and illuminates the entire world, happy are you.
There is a system called “the worlds.” The souls are hanging on it like fruit on the tree. There is a connection between the worlds (”tree”) and the souls (“fruit”), between the fruit themselves, meaning the souls, and between the parts of the tree, meaning Sefirot. They are all connected together, and all of them are merely Kelim (desires) and the Lights.
Likewise, all the characters described in The Book of Zohar: Rabbi Shimon, Rabbi Pinhas, Elazar, and the daughter of Rabbi Pinhas are the illuminations within the Kelim, tied together by certain connections. This is why The Zohar calls them by names of familial relationships, such as “grandfather,” “father,” “son,” “daughter,” or “wife” depending on who it is talking about.
However, all of this is related only to Kelim or the Lights. The Lights are most important. The illumination which emanates from one place to another is called “Rabbi Shimon,” “Rabbi Elazar,” or “Rabbi Pinhas.”
