I disagree with the authors that mystical experiences are at the base of these myths. For example, I think that death and resurrection were seen in nature with the changing seasons, in the circling stars, and in planting seeds, and not because of some mystical experience. Ritual Research reveals that repetitive rhythmic stimulation can drive the limbic and autonomic systems causing altered states of the mind like the transcendence of self. Uplifting congregational music can cause a mild degree of transcendence. Dancing, singing, chanting, and praying can all cause degrees of transcendence and bliss.
Rituals turn beliefs into spiritual experiences that proves their reality.
Mysticism Medical research proposes many causes for intense religious states, from fatigue, emotional distress, to obsessive thinking or mental illness. Psychiatrists believe that mystical experiences are illusions triggered by the neurotic regressive urge to reject an unfulfilling reality, and return to infantile bliss. These authors conclude the opposite. There are major differences between the spiritual experience and a psychotic episode. Other researches have found a link between epilepsy and spirituality.
