Zohar Acharei Mot
“וַיֹּאמֶר יְהוָה אֶל-מֹשֶׁה, דַּבֵּר אֶל-אַהֲרֹן אָחִיךָ, וְאַל-יָבֹא בְכָל-עֵת אֶל-הַקֹּדֶשׁ, מִבֵּית לַפָּרֹכֶת–אֶל-פְּנֵי הַכַּפֹּרֶת אֲשֶׁר עַל-הָאָרֹן, וְלֹא יָמוּת, כִּי בֶּעָנָן, אֵרָאֶה עַל-הַכַּפֹּרֶת”
“YHVH said to Moses: “Tell your brother Aaron that he shall not enter at any time into the holy place inside the veil, before the mercy seat which is on the ark, or he will die; for I will appear in the cloud over the mercy seat.”
Rabbi Shimon explains that God wanted to warn Aaron so he wouldn’t follow the mistake of his sons. The Holy Tabernacle is the ultimate tool to draw Light to the world but there’s a system and a process to follow. Aaron and the priests cannot enter the Holy at any time and they must come with the support of the Shechina.
Malchut is the aspect of time with pure and impure sides. The pure side is the Shechina that can connect us to the YHVH name through the Yod of Yessod. The impure side is negative and cannot receive Light from Yessod.
When it says ‘any times’ it means that Aaron cannot come with the negative side of Malchut. He must connect to the Shechina that supports the connection to Yessod, providing a proper vessel for the Light.
A man (Zeir Anpin) can come to his wife with proper consciousness and when her vessel is ready for unification. Then the Light from the Holy of Holies (Keter) activates the Right and Left brain (Chokmah and Binah) to form the life energy (Da’at) that flows down to testicles to transform the spiritual energy into matter and channel it through the penis (Yessod) into the vessel of the woman (womb, Yessod of Malchut) to create new life/energy/light/blessings in this world.
The consciousness of the unification is the aspect of the Shechina that helps in drawing positive and fruitful Light. Without the proper consciousness the unification is wrong and produces negative outcome.
Man cannot have unification with the woman at any time, because half of the month she’s under process of judgment. To make a good connection the man must use the right words (prayers) to build and open the path to the vessel.
I am bringing this kind of explanation to this process to teach another important Kabbalistic principal. Kabbalah explains the unification of Light and Vessel as unification man and woman.
“וּמִבְּשָׂרִי, אֶחֱזֶה אֱלוֹהַּ”
“From my flesh I will see God”
The word ‘my flesh’ in Hebrew ‘בשרי’ has the initials of Rabbi Shimon Bar Yochai and Kabbalists refer to this verse as a code. It reveals that the knowledge of Kabbalah that was brought to us by Rabbi Shimon in the Zohar gives us the ability to see the system of God and how the Light is revealed in the world.
