This book offers a novel philosophical system - Sufi Phenomenology - rooted in the shared pursuit of essence and truth within two major traditions: Sufism and phenomenology. While these traditions have historically been studied separately, their intersection reveals profound insights into consciousness, experience, and the nature of existence. By adopting phenomenological terminology and integrating Sufi metaphysical insights, this text introduces a fresh perspective on reality, bridging rational analysis and spiritual intuition. Sufi Phenomenology emerges as a distinct philosophical approach that reinterprets fundamental phenomenological structures through the lens of Sufi thought and explores key themes such as the nature of Eidos, Aʿyān-i Thābita, Consciousness, Reason, and Logos, illuminating dimensions of existence shaped by spiritual experience. This book is essential for scholars and students of phenomenology, Islamic philosophy, and comparative philosophy, as well as those exploring the intersections of science, spirituality, and human cognition. By offering a new paradigm that harmonizes Eastern and Western thought, Sufi Phenomenology opens new pathways for philosophical inquiry and personal transformation.
