Mercury represents our rational mind and is the planet of everyday expression and communication. It signifies our curiosity and what areas of life we find mentally appealing and stimulating. It analyzes and organises and defines the way we interact with others. Mercury in your chart reveals how you get your point across and in what style.
Mercury Square Pluto
The square can give you a harshness of temperament and expression, where your direct, blunt style can often create conflict and confrontation between yourself and others. Even though you prefer to reflect yourself as one capable of handling the 'real situation', you tend to lack a sensitivity towards possible reactions to your potentially penetrating insights. You rarely 'wrap' them up in socially acceptable packages for consumption, but offer them raw. There is a tendency to try to manipulate and mould any partner so that he or she conforms to your point of view; and often your views become intolerant and fixed, allowing little space for flexibility or change to occur naturally. Sometimes, in an effort to achieve your own will, you rely upon your strong will-power to dominate others. Sometimes this can succeed, but you are equally liable to apply it incorrectly through a lack of proportion and through insensitivity, creating more damage to your aims and others than you intended. Mentally, you require more self-discipline and understanding to make more positive use of your abilities of penetrative insight; in particular, the way in which you present yourself to others may need to be moderated. More control regarding your thoughts and words can help to avoid any controversy and unnecessary conflict with others, and help a redirection of your powers of insight inward, so that you can observe how you are projecting those negative shadow qualities out onto others in the world when these qualities should be being internally transformed and the energies released for positive applications.
Try to keep an open mind and avoid obsessive thoughts. You maybe preoccupied with things that are not of importance. Watch what you say to others and avoid forcing your point of view. It is good to try and be introspective then you may end up having greater awareness.
