Sanjiejiao

The Sanjiejiao ( "Three degrees religion") or Pufazong (普法宗 "Popular faith religion") was a religious movement based on the teachings of the Chan Buddhist monk Xinxing (信行, 540–594).

Teachings
Xinxing taught that in the last of the Three Ages of Buddhism, Buddhists must learn all the Buddhist teachings. He taught tapas (ascetic practices), begging for food, eating only one meal daily, worshiping all living things as Buddhas based on the doctrine of the Buddha-nature, building public charity "treasure houses" (無盡藏院) for monastics and laypeople alike, and sky burial upon death.

History
Based in Hua Du monastery (化度寺) in Chang'an, the movement was very popular in 600-700 CE. The monks lived in the Sanjiejiao house, or Sanjieyuan (三階院) inside Buddhist monasteries and built endless treasure houses. Its practices faced heavy criticism from many Buddhists and restriction by Buddhist Emperor Wen of Sui and Wu Zetian as unorthodox teachings. Emperor Xuanzong of Tang ordered the destruction of the Wujinzangyuan, the Sanjieyuan and the school's texts, sparing only the treasure houses. Bhikkhuni Zongjing (總靜) in the Zhixin monastery(直心寺) was a known practitioner who died in 831. Some texts, such as part of the three stages teachings (三階教法) were preserved in Japanese monasteries. Some were also found in Dunhuang texts and grottoes.
