AV, SaG, MaH and BaN are revealed from Adam Kadmon. AV corresponds to the Chochmah of Adam Kadmon and what exists here does not come within our grasp. It sends forth its light by way of the hairs of the head, through which the brain reveals its contents while itself remaining concealed. But SaG reveals the lights that are concealed in AV, and this is the emanation that constitutes Atzilut, which little by little becomes increasingly revealed. Accordingly, the inner light and encompassing light are initially far from one another, but they steadily come closer together, little by little, until they reach the mouth, where a Vessel is made. There the Likeness of Man is properly rooted, and this is the aspect of MaH and BaN that is revealed afterwards.
