Introducing the concept of the interactive field, Nathan Schwartz-Salant shows how the states of mind that can secretly undermine our relationships, both private and public, can become positive factors in transforming a relationship when brought to consciousness. Drawing on the insights of the ancient art of alchemy, he explains how a transformative process can be set in motion once the partners in a relationship learn how to enter the interactive field between them and discover the 'mad' states of mind that exist in every individual. This process of exploration increases mutual understanding, strengthens the relationship and releases creativity. The relating individuals are able to move beyond the apportionment of blame for 'wrongs' they perceive to be perpetrated by the other and which are often the unresolved cause of conflict between them. By acknowledging the subjectivity and states of mind that affect their reactions to one another and the existence of a 'third area' that affects both of them, they are able to transform a good enough relationship into a passionate and exhilarating experience. Illustrated by numerous clinical examples, The Mystery of Human Relationship builds on the work of Jung to create a thought-provoking and inspiring text for anyone who wishes to engage the mystery of growth within themselves and within their relationships.
