The Caduceus staff of Hermes
The two serpents in Caduceus represents the Pillars of Severity and Mercy while the central staff represents the Pillar of Mildness. The wings represents the Binah – Chokmah line, and with Keter as the top of the Cross.
In the Aquarian Mandala they wrote
“The Caduceus is the Staff of Hermes, the Spiritual Teacher of the Greeks and Egyptians known as Thoth-Hermes or Hermes Trismegistus. He is Mercury the Psychopomp – leader of souls to God. He is the Power of Fohat descending in spiral emanation through the Seven Planes.”
which clearly tells the same story as the Kabbalah Tree of Life.
I have later found this picture, but without text:
so i am not the first with this idea.
Here are an Egyptian Winged Disk, the emblem of the Sun, with Eagle Wings and two Cobras, showing its likeness to the Caduceus and to Isis with wings:
The Winged Disk
The Kabbala Tree of Life with the Angelic Hierarchies as mentioned by Paul.
Each of these circles, Sephira (Sephirots is plural), is a creation, with Man as the lowest creation. A diagram for angels would have the Angels as lowest Sephira. Angels are defined by having the Ether body as the lowest layer, which we have as the second lowest layer. The layers are described here: Dream Interpretation in Esoteric Work
The left pillar are the feminine, Yin, the forming principle, and the right pillar the masculine, Yang, the creative power, and the central pillar the androgyne, the equilibrium between the left and right pillar, consciousness, life.
What defines the Creation called Man is that the lowest layer in man is the physical, which means that minerals, plants, animals, and man is part of the same creation.
