Adam HaKadmon - Until the world was created, the was only Him and His Name, He wanted and contracted His light to create creation, gave them a place in which there is no thing without its place, found a place that is equal to all. And the Eyn Sof, Blessed be, surrounds it from all sides. And a line comes out from Him from one side, opens and enters and makes all the levels. There are ten levels, impossible to be quantified. Ten circles, and their rightness is in their midst/center, through them the qualities of the Place [are expressed], He directs all creations with justice, and punishes and rewards, and restores all evil into good. And brings His creations to His will. And so it says "I am first and I am last and there is no power besides Me" (Isaiah 44:6). All that the Holy Blessed One created in His world was created solely for His honor, as it is written " All that is called in My Name, I created, I formed, I made" (Isaiah 43:7) and it says "Ad-nai will reign forever" (Exodus 15:18)
