Biodynamic Craniosacral Therapy (BCST) is commonly seen as the spiritual approach to craniosacral therapy (CST); in fact, BCST as taught by Franklyn Sills, the pioneer in the field, is quite different from conventional CST. Biodynamic work is based on the development of perceptual skills where the practitioner learns to become sensitive to subtle respiratory motions called primary respiration and also to the power of spontaneous healing. Through the Breath of Life, which, Sills asserts, echoes the Holy Spirit in the Judeo-Christian tradition, bodhicitta in Buddhism, and the Tai Chi in Taoism, students of BCST learn to enter a state of presence oriented to the client's inherent ability to heal. In Foundations in Craniosacral Biodynamics, Sills offers students and practitioners an in-depth, step-by-step guide to the development of perceptual and clinical skills with specific clinical exercises and explorations to help students and practitioners learn the essentials of a biodynamic approach.
