Religious emotions and experiences occupy a large place in the life of a believer. Religious preachers skillfully use a person's mental experiences, taking him into the world of religious illusions, often use certain features of the human psyche to involve people in the bosom of the church. Therefore, the study of religious psychology is so important. The book of the prominent Soviet psychologist, Honored Scientist Professor K.K. Platonov, is devoted to important moments of religious psychology. The book is not a systematic presentation of the subject of the psychology of religion. As in "Entertaining Psychology," in his new work K.K. Platonov gives a lot of very instructive and interesting facts and shares his thoughts that arise in connection with this or that phenomenon of religious psychology.
