Krohn discusses the evolution of religious studies, emphasizing the collection and preservation of oral traditions, such as old runes, which serve as vital evidence of pre-Christian beliefs. He notes the scholarly contributions of previous researchers in this field and sets the stage for his exploration of Finnish mythology, shamanism, and the connection between ancient practices and modern beliefs, asserting that a comprehensive understanding of this topic requires a comparative approach with similar spiritual traditions from other cultures.
