the Messiah is described as the ‘central column’ (i.e., of the Sephiroth system), and of this column it is said: ‘The column of the centre is Metatron, whose name is like that of the Lord… it includes all gradations from Above to Below and from Below to Above, and binds them together in the centre.’
Jung cites the Zohar’s identification of the Messianic ‘central column’ with Metatron as a Kabbalistic parallel to the Paracelsian Original Man, establishing the column as a cosmological axis binding macrocosm and microcosm.
