We should understand what “Pharoah” symbolizes. The Creator created the will to receive as “existence from absence (Yesh Mi Ein),” meaning slightly different from the Light, only to separate them from each other.
All other things existing in the will to receive, except for this point of creation, are the Creator’s opposite forms. When the Light arrives and gives the will to receive its attributes, they transform within it into contrary attributes.
The entire essence of the will to receive is that it turns the Light’s attributes into the opposite ones. That transformer is called “existence from absence.” Actually, the will to receive only has that single attribute: to invert what arrives to it from the Creator. Thus, it turns out that everything existing within the will to receive, other than that single attribute of “existence from absence,” all of it is the Creator, only in an opposite form called “Pharaoh.”
