And when YQV”Q is without Its Shekhinah, it is stated of it: (Deut. 4:24)... for Y”Y ELoQeYKha is a consuming fire... For It takes from Gevurah to burn the world: Yod י is made into a burning coal, Vav ו is the flame of the coal, Hei and Hei ה־ה: one is the five colours, the second is the five lights that shine through them.
And when higher Hei is withdrawn from lower Hei, She says: (Song. 1:6) Do not look at me for I am blackened... But when it shines with Her colours, it is stated of Her: (Gen. 9:16)... And I shall see it to remember the eternal covenant.
