The central argument of the author is that despite the modernization and spread of official western religion the profane religion still exist and influences the lives of many people. There is peaceful co-existence of both the official and non-official religion in the society today. The unofficial religion exist and cannot be written off because it is the kind of religion that the people recognize with and gives them a sense of pride and culture and thus must needs be handed down over generation as a tradition. Secular theorists tend to say that there are people affiliated to religion differently but the truth of the matter and the fact is that though the religion may have declined and the society becoming more secular at the societal level it still exists strongly at an individual level.
Like their ancestors, modern Koreans are steeped in the tradition of fortune tellers on their personal concerns. The number of fortune tellers and shamams is more than double the combined total of Buddhist and Christian clergy. The author such numbers to indicate the difference and relative numbers between the performers of official and non-official religions. The author shows that although official religion is widely spread the initiation to unofficial religion still exists in different forms as they used to in the ancient days.
The arguments that non-official religion and official religion coexist among the people of all nations is viable and true since the modern religion only finds an already religious society only unorganized but highly ingrained in the people.
