The moon represents our emotional nature, our security and deepest needs. It containts our basic habits and unconscious reactions related to our past karma and upbringing. It is associated with the mother and with feminine energy in general, it is both our inner child and mother. It is responsive, receptive, reflective and instinctual. In our personal chart it shows how we respond to our environment emotionally.
Moon Square Mercury
The square aspect between the Moon and Mercury indicates inner tension, stress, and frustration, and a need for a radical inner adaptation to rebalance these two conflicting energies. Conscious change is required to overcome conflict between your conscious mind and protective lunar habit patterns. One likely imbalance is an unconscious lunar domination of your rational mind, where thought processes are subverted by deep emotions and feelings, with a consequence that decisions, judgments, or objective evaluation are influenced by emotionally charged attitudes. Such unconscious attitudes and values - possibly absorbed during early childhood or from parents - can condition present choices, where issues of the past still dominate your current life. Simply put, head and heart can be in constant conflict within you; decisions may be made according to which is dominant at any given time. This temporary supremacy can vary, like a pendulum movement, and may also be related to the sign, house, and element that each planet is in. It may be that one planet consistently dominates, and the other one becomes repressed. If Mercury dominates, then the Moon activity can sink deeper into the unconscious mind, influencing you more subtly and pervasively from a hidden position where the emotional coloration is less noticeable to you than to others. If Mercury is repressed, then rationality and logic may diminish, and choices may be influenced by insistent emotions, instincts, and feelings; habit patterns may often be security-biased. Sometimes you may observe that, when attempting to restore inner balance, Mercury begins to excessively rationalize feelings and emotions. If this is allowed to persist, you may start to deny the validity of your emotions and feelings, and in so doing repress your Moon sensitivity, creating another imbalance. Inner tension can reflect insecurity and self-doubt, creating highly nervous activity prompted by disharmony between the personality's conscious and unconscious levels. Sometimes this can manifest as psychosomatic illness, especially nervous illness, digestive problems, and diseases related to the activity of body fluids. Another problem could emerge from self-centeredness and separative ways of living and expression. You may rely on fixed attitudes, thoughts, beliefs, and values for a sense of stable security; but these can also create relationship difficulties if you act inflexibly. Whenever someone else's opinion differs from yours, you may react with aggressive defensiveness, without first considering the value of another point of view. You hate suggestions from others that you may be wrong, as this makes you feel insecure. Your response to this is often defiant and compulsively assertive. Paranoid feelings often accompany this reaction; and you can be very touchy emotionally, often triggering off misunderstandings and communication breakdown. With strangers you always feel insecure and on the defensive; even with closer friends, acquaintances, and family this pattern persists, although with les belligerence. Yet even in the family home, you react against having to change to accommodate others. Self-centeredly, you believe they should change to suit you;; the fact that they may not wish to do so is apparently of little concern to you. Yet you can often communicate quite well with those with whom you feel safe, often revealing a touching if slightly immature and sentimental emotionality about such relationships. Your hidden dependency on such intimates may not always be realized or acknowledged. Relationships would improve if you were less self-preoccupied, seeing others' needs as being as important as your own, and giving to others what you are so busy taking for yourself. Attention needs to be directed externally for you to become aware that others have equal needs and difficulties. Through mutual support, all can benefit and have a more enjoyable life. Sometimes your needs and concerns can become obsessive; and you rarely see that this represents immaturity and lack of integration. Ways that you evade making necessary inner changes can include obsessions with trivia and matters of inconsequence, continual chatter, which can create unsatisfactory relationships and wastes energy instead of using it positively to change internal stress through self-understanding. Mercury is often repressed by a dominant Moon whenever issues of personal security dominate life, much like a demanding infant wanting immediate satisfaction. Because of this, you can lack rationality and objectivity, as noted in signs of immaturity, a lack of self-understanding, and a surfeit of emotional bias. Sometimes your ability to discriminate between reality and illusion, fact and fiction, is weak. You can often be full of unresolved questions, uncertain of what you really think and feel about life and people, even though you defend whatever thoughts you are presenting. There can be a state of 'life-confusion' which persist
Your feelings may overwhelm your rational intellect making your thinking too subjective and hard to relate to. You feel strongly about expressing yourself and tensions should be released.
