Rabbi Elazar and Rabbi Aba were walking to see Rabbi Yosei, son of Rabbi Shimon son of Lakunia, who is the father-in-law of Rabbi Elazar. They rose at midnight to study Torah. Rabbi Elazar said that this is the time that the Holy One Blessed be He enters the Garden of Eden to entertain with the Tzadikim.
Rabbi Aba asked about what type of entertainment that is. Rabbi Elazar didn’t want to reveal the answer and said that this is a concealed secret that is not known to others. Rabbi Aba insists and said that there were great Tzadikim that sought to know this secret and almost certain that they found out this secret. For that reason, you need to reveal it.
Rabbi Elazar opened and quoted Isaiah 25:1
“יְהוָה אֱלֹהַי אַתָּה אֲרוֹמִמְךָ אוֹדֶה שִׁמְךָ כִּי עָשִׂיתָ פֶּלֶא עֵצוֹת מֵרָחוֹק אֱמוּנָה אֹמֶן.”
“O YHVH, You are my God! I will exalt You; I will praise Your name. For You have worked wonders—plans formed long ago—in perfect faithfulness.”. He explains that the name YHVH is a supernal secret. It is the beginning of the concealed supernal point that is unknown. It’s the Father and Mother, which is Chokmah and Binah that comes from theי Yod. It is the beginning that is in the question. Because this point is concealed, there’s no one to answer the question. Even though the question is a step toward revelation, the Light from the concealed point comes out to Chokmah and goes back. Chokmah cannot be revealed in its place, only after its light goes down to Zeir Anpin and Malchut.
Keter is the point that connects the Tree of Life to the Endless Light. Keter opens for the Endless Light to go into Chokmah and then closes. Chokmah then immediately push the Light to Binah that stores it and deliver it down to Zeir Anpin and Malchut. Only when the Light comes out of Binah we can tell/reveal it.
