Kabbalah su Numeri 24:11

The three heads of Atika
Three heads were engraved within each other, that is, the concealed Chochmah within the skull, and above each other, that is, the unknowable head above the skull. He explains, one head is concealed Chochmah, which is covered and unopened. This concealed Chochmah is the head for every head of any other Chochmah. This is the first head going upward. The second head is the upper head, the most concealed Atika Kadisha. It is the skull of Arich Anpin. The third highest head is the beginning of every beginning, a head that is not a head. That is, a head denotes the beginning of expansion and comprehension; yet nothing of this head is comprehensible, because what is inside this head does not know, nor is it known, since it is attached to neither wisdom nor understanding. Hence it is called, “Therefore now flee to your place” (Bemidbar 24:11), “And the living creatures ran and returned” (Yechezkel 1:14), because it is incomprehensible.
