Psychochirology -- the study of personality structure by means of reading the hands -- can reveal the present psychological situation, parental characteristics and influences, inherent and acquired patterns of behaviour and capabilities, inner conflicts of all natures and their potential for integration, as well as possibilities for growth. Each finger and mount portrays a different masculine and feminine archetypal figure, and they are always in flux. Getting to know them becomes a means of self-awareness, and in a therapeutic setting can also be a diagnostic tool. The hand holds our individual myth like a personal key: how can knowledge of this key lead to our own transformation?
