I do not lay claim to being a great Astrologer. In that regard I humbly defer to other bloggers on this site whose calling it is to cast horoscopes. I also realize that people born under the same sign can differ quite a bit in personality because of numerous other influences - rising signs, moon signs, etc. - which are usually different, while those same elements can make people of opposing signs more akin than one would normally expect.
I'm even aware that the Vedic Astrologers of India don't go by the month you were born; they determine your astrological sign by the month it was likely you were conceived! So there are many variables in this ancient field of study.
However, as a former Rosicrucian, I find it instructive to note that my metaphysical forebears - the Alchemists of the Middle Ages - rather simplistically assigned the following "humors and elements" to the various zodiacal birth signs:
The Great Secret is that the most esoteric teachings of Creation are hidden in plain sight. How else could the Powers That Be ensure that the uninitiated would never believe them?
The founders of esoteric societies were fond of creating abstruse rituals, mainly to give initiates the impression that they were experiencing something unique. Your mystery school may possess hidden knowledge - but every wisdom tradition on earth has discovered the same principles under different names.
Before I finally discovered that Paganism was the path I had been seeking, I was a 10th Degree Rosicrucian and a 3rd Degree Mason. I found the Rosicrucian teachings so comprehensive, and AMORC's correspondence staff so patient and generous with their time, that I was appalled, recently, to see Internet blogs trashing the Order.
