In this paper I argue that every learning situation may be based on an implicitly religious essence. It may be visible in experiential education, which utilizes challenge, adventure, and other unsafe situations intentionally and purposely. According to Rudolf Otto, the sacred as well as religion is characterized by awe and trembling ("mysterium tremendum et fascinans"). Whenever I want to learn anything new, I enter into uncertainty. Just as a comfort zone, safety, and security are valid for high-risk situations or extreme sports, they are also legitimate for any learning situation.
