A renewed interest in psychedelics for psychiatric conditions highlights experiences of awe, connectedness, and spiritual transformation, often described as among the most significant in life. Users may feel they encounter absolute truth and a deeper reality, akin to Wilfred Bion's concept of 'O', which denotes contact with absolute truth through intuitive awareness beyond cognitive knowing. The state of surrender and transcendence of cognitive, sensory-bound reality is key to such mystical experiences. This paper outlines the neurophenomenology of psychedelic use and the concept of O, drawing parallels between psychedelic-induced insight and the reshaping of perspectives that occurs in psychoanalysis or psychodynamic therapy.
Classic psychedelics and MDMA are increasingly studied for treating mental health conditions, with users often reporting profound experiences of awe, connectedness, and spiritual transformation. This article applies Wilfred Bion's psychoanalytic concepts, particularly his theory of containment and the K link (knowledge), to neurobiological models of the mind and the effects of these drugs. It discusses how early adversity affects neurodevelopment and neural circuitry, leading to hyperarousal and rigid cognitions, and reviews literature on using these substances for trauma- and stressor-related disorders. A Bionian lens may enrich understanding of how MDMA and psychedelics facilitate therapeutic change in trauma treatment.
