Important insights about how to develop human potential are being discovered these days in a field called transpersonal psychology. This new field is called the fourth force in psychology because like psychoanalysis, behaviorism, and humanistic psychology before it, it is on the cutting edge of what it means to be fully human. It seeks to develop a comprehensive understanding of human nature which also takes into account the dynamic role of motivation and the human spirit in the equation of excellence, well-being, and dynamic living. Transpersonal psychology seeks to understand how imagination, inspiration, intuition, creativity, and insight operate. These human resources provide what are called higher states of awareness because they help people view their lives from a higher point of view; clarify their values; strengthen, regenerate and renew themselves at the deepest levels; touch and empower the human spirit; and help them experience a sense of the unity which underlies all creation. Transpersonal psychology seeks to learn how to develop these human resources because they play such an important role in personal, professional, and communal lives. (ABL)
