“Meditation Sickness” in Medieval Chinese Buddhism and the Contemporary West

A certain percentage of people report experiencing adverse mental and physical side effects from practicing meditation. Contemporary scientific literature and personal reports from meditators are beginning to document the phenomenon, but centuries-old Buddhist texts also warned about the dangers of “meditation sickness.” Writings from medieval China not only identify the adverse mental and physical symptoms that can arise in the course of meditation practice, but also explain why these occur and how they can be effectively treated.
