Esoteric Hitlerism blue pilled us. To the S.S. the Black Sun had a different meaning
So the failure schizophrenics at /fringe/, those who encouraged everyone to read faggot posers like Evola (ride the tiger and be pacified) apparently were victims of a massive blue-pills by the Jews post WW2. Much like "Ancient Aryan Aliens" TV shows.
The True Meaning:
The Black Sun would be better translated as the Black Center.
The astrological Black Sun is not a physical body, but a mathematically defined point in space. Since the paths of the planets around our sun are elliptical rather than a perfect circular, each orbit has not a single center, but two foci.
In the case of a planet orbiting the sun in an elliptical orbit, the sun usually occupies one of the foci of the planet's orbit. The second focus is an empty point in space. This empty focus is known as the "black sun" of that planet's orbit.'''
The SS used the symbol not as a sun behind the sun, or secret alien power source, but a FOCAL POINT of their order.
The abyss which new light sprang, a source of creation and destruction. No matter the seasons or changes in events, the center remained. 12 branches, the number of order. Think the center dot in a the cycle of time, stoic and balanced.
German Psychoanalyst Carl Jung wrote about the Black Sun or Sol Niger as it pertained to psychology in his alchemical works. Contact with the Black Center is associated with the experience of burning away the junk-data and hang-ups of the personality, leaving the gold or essential nature of the self.
Facing your darkness (fears, depression, regret, anxieties) and coming out a better person, with an inner-light. A maturity of the Soul.
(Much like the legend of Odin and the hanging tree, where he sacrificed himself to himself to learn the secrets of death the Ruin Magic (the oldest alphabet).)
It is analogous in some ways to the Abyss that lies before the maturity of self-understanding. The Abyss that Nietzsche described, stairs back at you in self-reflection. The failures before a new dawn that all those of good character, all protagonists in a story, must first overcome to fulfill their destiny. As one's destiny is directly tied to your self-discipline and character.
Dark Green, it contained the eye colors of all Aryans (blue, green, hazel). As the Black center is a symbol of the human eye.
