This reminds us of the Egyptian sequence: Pharaoh, ka, God. The triune stone consists of ‘three different and distinct substances: Sal-Mercurius-Sulphur.’ As the Egyptian mystique of kingship shows, the king, like every archetype, is not just a static image; he signifies a dynamic process whereby the human carrier of the mystery is included in the mysterious drama of God’s incarnation.
Jung reads the Egyptian triadic sequence Pharaoh–ka–God as a structural parallel to alchemical triunity, arguing that kingship is not static symbolism but a dynamic, incarnational psychological process.
