Grounding is a concept in Bioenergetic Analysis which refers to a person's relationship to reality. This relationship is thought to encompass all aspects of reality, external physical reality as well as internal psychological reality. Using this conceptual framework, an effort is made to link the somatic structures and processes to the psychic structures and processes which go into the perception and understanding of reality. In this paper that framework is applied to the concept of grounding in people with borderline personality organization. Experiential, clinical and theoretical data are blended to elucidate both the experience of reality and the structural underpinnings of that experience in people organized in this way. Clinical interventions drawn from this theoretical standpoint are described, particularly as they relate to development of the ability to apprehend reality more fully.
