Every civilization falls the same way, not by external invasion but by infection of the mind. PARASITE: Fall of the Chosen is a groundbreaking psychological treatise that exposes how thought itself becomes host to distortion, and how humanity can reclaim its coherence before consciousness devours its own creation. Dr. Salahadhin, a behavioral and cognitive psychologist, dissects the anatomy of corruption through the lens of mental parasitism, a condition in which belief feeds on emotion, ideology replaces perception, and pleasure anesthetizes empathy. Moving through twelve profound chapters, the book traces the entire life cycle of distortion: from the illusion of superiority to the collapse of empathy, from collective narcissism to cognitive autophagy, and finally, to the renewal of conscious integrity. Blending scientific insight with humanistic depth, Salahadhin reveals how the same neural and emotional mechanisms that sustain delusion can be repurposed for transformation. PARASITE merges the precision of cognitive-behavioral psychology with the moral architecture of self-awareness, showing that healing does not come through violence or denial, but through reintegration with truth. Written in lucid, lyrical prose, the book is both diagnosis and blueprint, a mirror held before the modern psyche and a manual for its recovery. It speaks to clinicians, scholars, leaders, and seekers alike: anyone who senses that civilization's noise has drowned the quiet intelligence of conscience. PARASITE: Fall of the Chosen challenges readers to confront the seductive systems that shape their thinking and to rediscover the sovereignty of reflection. The fall of the chosen is not an ending, but the beginning of awareness itself, the mind remembering what it means to be whole.
