Pure astrology here...  Moon/Mercury interactions.  The Moon represents your feelings, emotions, sensitivities, habit patterns and general day to day life, it's your basic personality.  Mercury is the way you read, write, speak, travel and move, it's communication at all levels, whether mental, verbal or mobile.  If you have these two sextile or trine in your chart, there is a blend of the mental and the feelingful that gives a balanced perspective on the world.  A conjunction of the two blends the mind and the feelings, whilst the opposition between the two creates a kind of fusion when the person is constantly torn and has to act rather than think or feel.  The square produces the person who plans things but fails because they don't feel like it at the time, or who feels something strongly but the rationalises it away.  Sometimes the intellect and the emotions are different sides of the same coin, and it takes a crisis of confidence to realise that imbetween the two lies the internal knowing, the internal learning, the in-tuition.  When all else fails, trust the body - although dancing helps, right?
