The Moon is the fastest celestial body that is used in astrology. It completes is cycle around the zodiac in 28-29 days, unlike the Sun and other planets, which take much longer. This, along with the Moon being the satellite of the Earth, makes it reflect on our most intimate and most unique characteristics.

While the Sun shows our central sense of individuality, ego, our sense of Self, the Moon is the personalized reflection of the Self, which is our mind and emotions, along with all the conscious and subconscious patterns within the two.

In the west the common questions "What's your sign?" always refers to the Sun's position in the Tropical Zodiac, while in the East the same question refers to the Moon in the Constellational Zodial. The Moon in Vedic Astrology is much more important the the Sun when it comes to predictions or compatibility evaluations.

We know that the Moon has powerful effect on the life on our planets. Wolves howl at it when full, the tides of the oceans drastically impact our lives, and the correlation between the Moon's phases and crime rate has become a socialogical study, and often used by law enforcement.
