The position of the Moon in a horoscope is second in importance only to the position of the Sun.
In astrology, the Moon is indicative of personality, individuality and the unconscious. It represents instinctive reactions and the side of an individual that will respond to a given situation without prior thought or consideration.
Based upon the theories of Sigmund Freud, it is the id, whereas the Sun sign of an individual is the ego.
Moon personality is one which a person keeps hidden
In many respects, the Moon personality is one which a person keeps hidden and may even represent a nature considered to be somewhat disturbing, uncivilized, primitive or animistic.
In short, the Moon personality is an individual's inner core...the area which experiences hate and jealousy, is brooding and fearful and may indulge in fantasies that a person will deny even to himself or herself.
It can also reveal much regarding the manner in which an individual was nurtured and cared for
Nonetheless, this Lunar influence is usually a somewhat subtle one, relating to a personality which is beneath the surface. It can also reveal much regarding the manner in which an individual was nurtured and cared for...as well as how he or she perceives his or her mother.
Reveals special elements to the character of an individual's Sun sign
In a horoscope reading, the Moon modifies the Sun sign, bringing into play new forces, different motivations and special elements to the character of an individual's Sun sign. The effect of a person's Moon sign can significantly decrease or increase the tone of a Sun sign.
Since the Moon itself is feminine, its influence seems to affect females more strongly than it does males. In the man, the strength of the Moon influence tends to indicate sensitivity more than any other facet of the personality.
The Moon travels through all twelve Zodiac signs during every twenty-eight days.
