Аннотация:Abstract The psychology of religion and B uddhist psychology have deep historical connections. However, there has been a lack of discourse between these fields of study. Therefore this paper focuses on the relationship between the psychology of religion and B uddhist psychology as well as the history and research trends of each field. Recently, studies on the psychology of religion and B uddhist psychology have attracted attention based on the concepts of “spirituality” and “mindfulness.” Moreover, there have been a number of psychotherapeutic techniques developed that are based on mindfulness meditation. The relationship between the psychology of religion and B uddhist psychology is complex and often the subject of confusion. The complexity results from the fact that B uddhism could be seen as an alternative to psychology in the analysis of the mind; and moreover, B uddhism also contains aspects of psychotherapy that bring peace of mind.
