My knowledge of astrology and astronomy is still very much that of a novice, or perhaps journeyman. I've only toyed seriously with the legitimacy of astrology for the last 3 years or so. My awareness of its legitimacy has grown in successively greater stages.
I've learned a little bit about things like houses and signs and whatnot but mostly my understanding of astrology derives from physics concepts like the right hand rule of electromagnetism, rhythm entrainment, constructive & destructive interference, and the interaction of magnetic fields.
I studied Yuga Cycles a little bit but it's been a while.
I need to commit to finishing some of my other studies (like the Kabbalah/Tarot textbook I'm halfway through) so I can have the mental RAM available to dive into astrology/astronomy more. Whenever I do get my eventual bunker property, I want to set up some kind of personal observatory.
