A represents the Father Principle, F the divine outflow, G the point of influx into the twelve orders of spirits (probably Sagittarius). The letters H, I, J, K, L, M, N, O, P, Q, S, and T denote the sequential points of irradiations to each other; W and X, the World of the Sons of God; and B, C, D, and E, the World of Lucifer.
This plate shows the universe after the descent of Lucifer into matter. According to von Welling, when Lucifer wanted to control power, the influx of the divine light instantly ceased.
Lucifer's world (which later became the solar system), with all its legions of spirits (who in their essence were Schamayim) reflecting his ideas and inverting the divine light, was turned into darkness.
Lucifer's Schamayim thereupon became a contracted disc, a tangible substance; and Chaos came into existence.
