To the editor: On May 13, 1992, in his hometown of Changchun, China, Master Li Hongzhi introduced the practice of Falun Dafa to the public. Over the next two years, he traveled throughout China giving nine-day lectures on the practice. May 13 is now celebrated as World Falun Dafa Day by Falun Dafa practitioners. Falun Dafa (or Falun Gong) is a spiritual discipline that combines slow moving “qigong” exercise, meditation and an emphasis on three principles: truthfulness, compassion and forbearance. China has a long history of “self-cultivation,” and Falun Dafa was recognized as something from traditional culture. Since it is taught free of charge, within 7 years of its introduction, an estimated 100 million people were practicing.
