The peak experience in this article is most clearly described by Rousseau as a celestial fire that consumed him. It unleashed his creativity. He then reformed his habits and his dress to the simplicity he advocated. The author disagrees with Maslow who stresses that a peak experience is pleasant and occurs in mature, self-actualized people. Blanchard gives examples from Varieties of Religious Experience by William James where the peak experience is associated with uncanny terror. He also refers to Sartre and to Erikson's study of Martin Luther which portrays peak experience in the form of identity crisis.
