Here are the three color stages of the coniunctio: the nigredo, the albedo and the rubedo; and out of this sequential process the spherical filius is born, the ''Ruddy Son.'' The Ruddy Son is symbolically equivalent to the globe, the rotundum that's born out of the square bed. Verse 29: [Image: 96f6cb7cf38e59e4dffd0b98c5202b51.gif] [Image: 96f6cb7cf38e59e4dffd0b98c5202b51.gif] Hence God unlock'd the Gates of Paradise, Rais'd him like Luna to th'Imperiall Place, Sublim'd him to the Heavens, and that being done, Crown'd him in Glory, aequall with the Sun. This reference to unlocking the gates of Paradise can be understood again in terms of the circle-square-circle sequence. Paradise is the first circle, the state of Page 201 original wholeness. The full development of the ego as an earthly material manifestation would be the square, but as Jung says in paragraph 439, in the square the elements are still separate and hostile to one another.169 So with the second circle, the four elements are unified into the quintessence and the state of original wholeness returns on a conscious level. This would correspond to a conscious return to Paradise. It's like the Messianic kingdom in which, according to Jewish legend, the Garden of Eden manifests itself again and grapes from the Garden of Eden are served at the Messianic banquet.170 So with the birth of the regenerated
— Edward F. Edinger
Edinger is tracking the oldest promise Western esotericism knows how to make: that the fragmentation you are living through is not the final word, that a second wholeness waits on the other side of the square's warfare. Circle, square, circle — Paradise lost, the hard rectangular life of separated elements, Paradise consciously regained. The Messianic banquet, the grapes of Eden served again. It is a beautiful architecture, and it carries the warmest possible current through it: if you suffer the nigredo long enough, redness breaks through, the Son is born, the gates unlock.
Notice what it asks of you before it delivers. You must believe the square is transitional — that hostile, separated elements are a stage, not a permanent condition. That belief is itself a form of relief, a way of metabolizing conflict by placing it inside a larger arc that resolves. The question the alchemists could never quite answer is whether the rubedo is a transformation of the square or an escape from it. Jung's own hesitation in paragraph 439 — elements still separate and hostile in the square — suggests he knew the difference mattered. Wholeness that bypasses the square's genuine separateness is not quintessence; it is a fifth element conjured to avoid the other four.
