Spaso-Preobrazhensky Solovetsky Stavropegic Monastery, 2024. This publication continues the series of books “Shield of Faith”, dedicated to overcoming post-traumatic stress disorder (PTSD) and anxiety arising from participation in hostilities (or from contact with information about them). People who have gone through difficult trials are faced with the question: is it necessary to remember the experience and, if so, how? If it is worth forgetting, then with the help of what technologies? These two paths will have completely different consequences. The book examines some physiological aspects of PTSD and shows that the presence of a semantic vertical allows a person to form immunity against the destructive effects of PTSD on the psyche.
