The Earth's Moon is second only to the Sun in order of importance in your horoscope. Whereas your Sun sign shapes you in outwardly visible ways, your Moon sign's effects on you are more subtle and internal. The Moon rules your emotions, dreams, and subconscious. It shapes your innermost fears, desires, loves, and needs. When the Moon is in harmony with the rest of the planets in your horoscope, your emotions and desires are in harmony with the reality of your life--you are personally fulfilled and emotionally stable. If the Moon is afflicted (at odds with another planet in your horoscope), your dark side tends to emerge (anger, jealousy, hate, fear, depression, etc.)

The Moon's diameter is about one-fourth that of earth, and its mass is about 1.23 percent that of earth. Having no free water on its surface nor any atmosphere, the Moon has no weather to alter its heavily cratered surface. And since the Moon rotates on its axis once per orbit around the Earth, the same side of the Moon always faces the earth. The Moon completes its elliptical orbit around the earth once every 27 days, 7 hours, 43 minutes, and 11.5 seconds (relative to the stars).

The ancients believed that the dark regions on the Moon's surface were oceans, giving rise to the Latin name "mare" (or sea) which is still used in the present day. They believed that the brighter areas were continents. With the advent of telescopes in the 17th century, astronomers discovered many features on the surface (craters, mountains, faults, rays, and domes). In 1969, the American Apollo 11 spacecraft carried the first humans to the Moon.

In Greek mythology, Selene was the goddess of the moon and sister of Helios, the sun god. She fell in love with a shepherd named Endymion and then lulled him into an eternal sleep so that he could never leave her.

Symbolized by the crescent Moon is a half circle which represent the sunconscious mind.  Magick works through the medium of the subconscious:  the realms of dreams, psychic visions, hidden desires and imagination.

As we know the moon has no light of its own but merely reflects the ray's of the Sun.  However these rays are changed by contact with the Moon and moonlight has a very different effect on the human mind than that of sunshine   In both astrology and magic the moon represents the hidden side of the human personality which under normal circumstances is not revealed to the outside world.

In general most magickal work is hidden (Occult) and is performed out of sight and in privacy.  It is an old adage the magick which is practiced in the public gaze will not be as successful as private workings.  This belief may date back to the old days of persecution when it was impossible to work openly.

In esoteric tradition teh Moon is likened with the widely held doctrine of reincarnation or the rebirth of the soul in a succession of different physical bodies.  according to some arcane beleifs, when the spirit leaves the bokewdy after death it travels to the Lunar world to be reborn.  In old pagan religions we have seen that the Full Moon was one of the mystic symbols of the Great Mother Goddess who according to the oldest creation myths, gave birth to the universe.

When the Magician uses Lunar Energy he is dealing with the ebb and flow of potent psychic forces. Lunar tides have both a physical and psychic affect on humans, animals, and flora.  It is therefore natural that occultly the Moon should symbolize the Subconscious mind of the Awakened person who can use it to bring hidden desires into manifestation
