A concise introduction to Islamic mysticism that traces its emergence from early ascetic practice and situates its development within Islam. It outlines key terminology and the stages of the spiritual path—renunciation, illumination and ecstatic experience, gnostic insight, and the primacy of divine love—then examines the role of holy persons, reports of miracles, and the culminating unitive state. The presentation pairs historical overview with translations of Arabic and Persian passages and critical commentary, and closes with a brief bibliography for further study.
