In Hazrat Inayat Khan’s teachings, the purification of the body leads to the purification of the breath, the purification of the breath leads to the purification of the mind, and the purification of the mind leads to the purification of the heart. The teachings in this volume touch on all four stages, with a primary focus on the purification of the mind. Alongside Hazrat’s teachings on the mind, the volume contains extensive lectures on the subjects of health and healing, lectures which anticipate the findings of contemporary mind-body medicine. Taken together, these chapters constitute a comprehensive overview of the fundamental principles of Sufi healing.
