From the legendary father of astrology, Hermes Trismegistus, in the Emerald Tablet:
“…. that which is above is the same as that which is below, and that which is below is the same as that which is above, for the performance of miracles of the One Thing. And as all things are from the One, by the meditation of One, so all things have their birth from this One Thing by adaptation..“
Basic foundation Principle
Astrology is founded on the principle of correspondence between the above and the below. Each reflects the other. We dance together with the planets and stars to the music of this unseen force, referred to by ancient astrologers as ‘the prime mover’. The rhythms in the heavens and on earth are the same.
It’s not a cause and effect situation between the celestial bodies and us, it just looks that way at first glance. What is really happening is that both what we see in the heavens and what happens on earth moves to the same tune.
Nature and Light
In its simplest form astrology is the correlation of nature in the celestial sphere with life on earth.
Etymology: Astro = star; ology = study or science.
Stars are points of light in the heavens and the word planet comes from the Greek word meaning wandering star. Thus the focus of astrological study is the celestial lights which include the stars, the luminaries (Sun and Moon) and the planets. The patterns formed by the celestial lights are correlated with events on earth.
In a basic sense astrology is the study of the lights in the heavens and how the patterns of their movements reflect events within us and in the world around us.
