Whereas the Sun represents the divine spark that descends into matter to create life, the Moon is the receptacle that receives that divine spark, the chalice in which life grows, the substance of which all things are made. This is why it is exalted in Taurus, for Taurus is the sign of matter, substance, receptivity and springtime, when the fertile Earth receives the outrushing seed of life. The Moon has no light of its own, but shines only by the reflected light of the Sun.
Where the Sun acts, the Moon reacts. How do we instinctively react or respond to problems? What do we feel we need for a sense of security? Look to the Moon in your natal chart for answers.
The Moon is associated with the mother and with feminine energy in general. The Moon is both our inner child and our inner mother. It is responsive, receptive, and reflective. The Moon is our spontaneous and instinctual reactions.
Just as the Moon circles the Sun, in a symbolically protective manner, and reflects the Sun’s light, the Moon in our chart shows how we protect ourselves, as well as make ourselves feel secure, comfortable, and safe.
We can also think of the Moon as that which gives us animation. It rules rhythmic ebb and flow of activity and energy. The Moon is a mediator between the inner world and the outer world. While the Sun is rational, the Moon is irrational. Habitual behaviors and prejudices are ruled by the Moon. Prejudices may not be acted out, as our Sun may censor them, but the Moon rules our spontaneous reactions and feelings.
For some of us, our Moons seem to drive our personalities more than the Sun does. This is particularly true if the Moon is in a water sign (Cancer, Scorpio, or Pisces), or if it is conjunct an angle in the chart (near the Ascendant, Descendant, 4th house cusp, or 10th house cusp). For true happiness in life, it is wise to neither give your Moon too much nor too little importance in your life.
The symbol for the Moon is the half circle of the personality, a reflection of our spirit or true self within, the Sun. Just as the light or energy of the Moon waxes and wanes as it goes through phases, so, too, do the affairs of the house in which it is placed. The Moon’s house shows where we feel and change the most, and those experiences to which our emotions are the most vulnerable.The Moon represents more things than any other “planet.” It symbolizes the feminine yin principle of receptivity, the emotions, matter and material substance, our mother-image, nurturance, personality, the past, home and family, heredity, childhood, children and young people, habit patterns, feelings of belonging and of alienation, memory, unconsciousness, the subconscious, public and mass consciousness, reflexive and instinctual behavior, women in general and the wife in particular in a man’s chart. In the physical body the Moon rules the stomach, breasts, solar plexus, pancreas, and all bodily fluids and the flow of secretions.
On the Earth, the Moon rules the tides and the ocean. Since the Moon depicts our general experience of having been nurtured, supported and taken care of, an afflicted Moon can lead to feelings of alienation and not belonging, of being estranged from this universe of which one is, by right of birth, a part. This can manifest in feelings of self-worth based on what you do and its success, rather than on who you are.
