Astrology uses the elemental sign of an individual as one of it's delineation tools. I got a general idea of the meaning of the Elements but never found any author who explained them in depth. I wondered why the Elemental signs were just mentioned and then set aside. I often wondered if the Astrologer felt they were too basic or they just didn't understand their relative importance. I soon found out that it wasn't that they were unimportant but that other delineations were more important than mere elemental signs.
Elemental signs are basic .
They are general or generic in their nature therefore only contirbuted to a basic generalization such as the Sun sign. Don't get me wrong, I am as guilty as the next since I have studied the subject. But, one of the first things I explain to those I read for is their Elemental Sign. This may be tempered by other factors but it is still a basic quality that can not be just mentioned and set aside. Once you know your elemental sign you will know your basic nature.
