As the ruler of the tides, it is fitting that in Astrology, the Moon is also the ruler of our emotions.
How we feel about things and how our emotions affect others are all influenced by the moon. Through the Moon's energy we endeavor to reconcile various emotions in order to make ourselves complete and one with the world.
In your Birth Chart, looking at your Moon information is as important as your Sun Sign information. The Sun gives us our Spirit & Energy, the Moon gives us our Soul & Emotions.
