And therefore, Adam Kadmon, which is the totality of everything, is the totality of this order formed in this likeness. We will see clearly below (Opening 31) that the entirety of all that exists is called Adam Kadmon (“Primordial Adam”). All of the worlds above and below are considered to be only parts of this, like branches emerging from the root. Everything in its entirety is this Adam Kadmon, and as discussed later, “The Ten Sefirot of Adam Kadmon fill the entire void”, as will be explained in due course with the help of Heaven.
Adam Kadmon as the Totality of Everything
