Part 2: Underlying the entire order is the archetypal Likeness of Man (דמות אדם, d’mut Adam)... Of the archetypal Likeness of Man it is written: “Let us make Adam in our image, after our likeness” (Genesis 1:26). We see that this likeness includes and encompasses all the powers of holiness.
...with his full complement of limbs... Just as each individual Partzuf divides into 613 lights, these being its 613 limbs and interconnecting channels, so too the totality of existence is made up of 613 limbs and channels, all of which constitute a single overall likeness. For even though each of the different worlds is considered to be a world in itself, they are all only limbs of this overall likeness. The interconnections and interrelationships between the different worlds are the interconnections and interrelationships between the constituent limbs of this single order. Thus – All are linked together in a single system, exactly as they are in man. The meaning of this should be clear in the light of what we have said above.
