What are demons? Are they mythical relics of ancient imagination—or energetic realities embedded in the very fabric of our being and becoming?

In Principles of Demonology in Sufi Metaphysics According to Ongoing Process Ontology (OPO), Adem Bilgin offers a groundbreaking synthesis of classical Islamic spirituality and contemporary ontological theory. Drawing from the deep wells of Sufi metaphysics, especially the teachings of Ibn Arabi, Al-Ghazālī, and Rūmī, and integrating the process-based logic of Ongoing Process Ontology, this work redefines demons not as static beings of supernatural fantasy, but as morphic distortions—fields of energetic, cognitive, and symbolic misalignment that emerge when the soul strays from divine resonance.

Across fourteen chapters, the reader is guided through the layered anatomy of jinn, shayatin, Iblis, and the nafs (ego), unveiling their psychological, spiritual, and bioelectromagnetic dimensions. From the ecology of cursed spaces and symbolic demonology in modern media to the neurology of possession and the spiritual technologies of dhikr, prayer, breath, and divine light, this book delivers a comprehensive vision of demonology as a science of sacred realignment.

Rejecting both superstition and reductive materialism, this volume proposes a bold framework for diagnosing, mapping, and countering spiritual interference using a unified language of mysticism, metaphysics, and scientific insight.

Whether you are a Sufi seeker, a scholar of consciousness, a spiritual healer, or simply a curious soul navigating the chaos of modern life, this book invites you to confront the shadows—within and without—and learn to walk the path of divine coherence.

"To know Iblis is to know the danger of knowing the self too much—and God too little."
