日本妖怪伝　サトリ

A psychotherapist suffers from the onslaughts of Satori, the demon whose name is paradoxically homonymic to the word used for enlightenment experiences in the Zen tradition. Many people mistakenly believe that such a state is the goal of Zen practice; however, the demon strikes at people who are in a state devoid of thought or feeling. Satori's influence spreads from the psychotherapist to a couple who grow increasingly uninhibited.
