In the beginning, when the Will of the King began to take effect, He impressed His signs into the heavenly sphere. Within the Most Hidden, the Infinite (En Sof), a dark flame issued forth, like a fog forming in the Unformed. Forming the concentric ring of that [first] sphere, [this flame was] neither white nor black, neither red nor green, of no color whatever. Only after this flame began to assume size and dimension, did it produce radiant colors. From the innermost center of the flame gushed forth a host of colors which spread on everything beneath. Concealed within all was the hidden mystery of the Infinite (En Sof )
