The imagery of the T'ai Chi figure and its associated trigrams can serve as a model for understanding the processes of change within psychotherapy. The T'ai Chi figure expresses the themes of unity and completeness, the dynamic interplay and balance of opposite forces, and the cyclical nature of therapeutic change. The images and attributes of the eight trigrams provide insights into the processes within the patient, the therapist, and their relationship. The epistemological power of T'ai Chi imagery lies in its ability to embrace the subtle complexities of transitional states as well as interpretive subjectivity as the exploratory pathway into the intrapsychic world.
