Hi Austin....its quite evident that you have no knowledge of the true system of ancient Astrological thought!
Now you take the 12 astrological signs for example, they represent the 12 main neurological nerves, located on the length of the spine and functionary to the Central Nervous System. Aries as a nerve represents functioning of the adrenals. Taurus as a nerve represents functioning of the thyroid gland. Gemini as a nerve represents functioning of the nerves in the right and left lung. Cancer as a nerve represents functioning of the alimentary canal. Leo represents functioning of the heart and spinal chord. Virgo as a nerve represents functioning of the brain and connections to the CNS. Libra as a nerve represents functioning of the kidneys and the lower spine in the lumbar region of the back. Scorpio as a nerve represents formation of cells in the reproduction system. Sagittarius represents the pituitary gland and functioning of the liver, also volition in locomotion. Capricorn represents functioning of the gallbladder, spleen, cells in bones, skin and teeth. Aquarius represents functioning of the pineal gland and entire circulatory system. Pisces represents the thalamus and its effects on the nervous system.
Furthermore, the Sun represents your right eye letting in light to the left lobe of brain. The Moon represents your left eye which functions with the right side of the brain. The earth represents your physical body. Mercury represents your brain and the fact that you can think. Venus resprsents your five physical senses and a higher sixth sense. Mars is your right ear and Saturn is your left ear. Jupiter represents gradations of consciousness. Uranus represents complex and possible interconnections of neural pathways in the environment of the brain. Neptune represents the esthetic domain of consciousness. Pluto represents the subconscious domain in the strata of consciousness.
Astrology is an ancient thought system about consciousness and I have studied it for many years. It would just be a laughing situation to you if I told you an Angel showed me the true Circle of Life....so I will spare you the whole story and tell you that sometimes life is not about what we believe but moreso some of the mysteries brought before us as we begin to challenge this thing we call belief....
