Tikkun 22 – 15

Psalms 25:14
“סוֹד יְהוָה, לִירֵאָיו וּבְרִיתוֹ, לְהוֹדִיעָם.”
“The secrets of YHVH is for those that see him with awe; and His covenant, to make them know it.”

The secret of the name YHVH is revealed to those who dwell in the name and study it. This study connects us to Yessod and opens the gate for the light to come down.
The first 4 letters of the verse are סוֹד י, meaning the secret of Y י, which refers to the 10 Sefirot that exist within the name. The 4 letters also spell the word יסוד, Yessod, which is the gate to connect to the Light.

י – Keter and Chokmah
ה – Binah
ו – Zeir Anpin (the 6 Sefirot: Chessed, Gevurah, Tiferet, Netzach, Hod and Yessod)
ה – Malchut

Jeremiah 9:22
“כֹּה אָמַר יְהוָה, אַל-יִתְהַלֵּל חָכָם בְּחָכְמָתוֹ”
“Thus said YHVH: Let not the wise man glory in his wisdom”

Having the wisdom about the system is not sufficient to connect to the light of the upper levels.

The next verse tells us what we need to do in order to achieve that
“כִּי אִם-בְּזֹאת יִתְהַלֵּל הַמִּתְהַלֵּל, הַשְׂכֵּל וְיָדֹעַ אוֹתִי–כִּי אֲנִי יְהוָה”
“But let him that glorieth glory in this (זֹאת = Malchut) , that he understand (Binah), and know (Da’at) Me, that I am YHVH”

God is telling us that ONLY with positive actions in Malchut we may climb the levels and enjoy the beneficent of his light.
The initials of the four words after בְּזֹאת, are YHHV, which is an elevated state of the name YHVH as it brings Binah and Malchut together.

Having the wisdom without translating it into actions in Malchut can only lead to an inflated ego. Sharing and doing for others without personal agenda draws the light and the feeling of humbleness from the gift and abilities you have to share with others.
