The sun is an aspect of consciousness, being a phenomenon partly linked with the ego and partly with the Self. One aspect of the sun is open to the unconscious, for the two rays imply a principle of consciousness capable of embracing the opposites, while the other sun is ‘a closed system’ it is one-sided and therefore destructive.
Von Franz articulates the foundational Jungian distinction between a solar consciousness aligned with the Self (two-rayed, embracing opposites) and an inflated, ego-bound solar consciousness that is destructively one-sided.
