 Mysticism becomes “naturalized.” It is reduced from a full way of life to eliciting mystical experiences for limited benefits or as mere recreation. Mystical experiences break the sense of a narrow “self’” and makes one feel connected to others and the rest of the world, and secularists see this in terms of the natural world alone. This naturalist spirituality appears more tied to mystical experiences than other psychedelic experiences (Letheby 2021, 200). Patients often attach great spiritual importance to mystical experiences even if their metaphysics remains naturalist (see Griffiths 2011). Mystical experiences often touch off awe and wonder at the universe and being alive and also an interest in the “big questions” of philosophy and science even if the experiences themselves are not taken to be cognitive. That mystical experiences may involve transcendent realities or may give knowledge of reality is either denied in favor of a naturalist metaphysics, or the issue is simply ignored. In fact, while mystical experiences are normally seen in terms of transcendent realities, these experiences may lead those inclined toward naturalism to becoming convinced that there is no god or life after death and to abandoning religion entirely (Newberg and Waldman 2016, 60, 67–81).
