Tikkun #13 continue
The Shechina provides protection from The Snake, which is the head of all negativity, Sam-ael.
Psalms 91:4 “..Under his wings you shall take refuge…” . The wings are the two H ה of the name YHVH. One wing for the lower Shechina, Malchut and one for the H of Binah, the upper Shechina.
To have the protection a person should elevate himself to the level of Yessod of Zeir Anpin, which is the Vav of the name YHVH to have the two H as wings protecting from both sides.
At the Yessod level there is a point of the 18 Sefirot of direct light and returning light are met. Nine Sefirot from Keter to Yessod and nine from Yessod to Keter.
This is the light revealed in Malchut to bring life, 18 id the numerical value of Chai חי, which means life.
