TheSanjiejiao (Chinese:三階教 "Three degrees religion") orPufazong (普法宗 "Popular faith religion") was a religious movement based on the teachings of theChan Buddhist monk Xinxing (信行, 540–594).
Xinxing taught that in the last of theThree Ages of Buddhism, Buddhists must learn all the Buddhist teachings. He taughttapas (ascetic practices), begging for food, eating only one meal daily, worshiping all living things as Buddhas based on the doctrine of theBuddha-nature, building public charity "treasure houses" (無盡藏院) formonastics and laypeople alike, andsky burial upon death.[1]
Based in Hua Du monastery (化度寺) inChang'an, the movement was very popular in 600-700 CE.[2] 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 BuddhistEmperor Wen of Sui andWu Zetian as unorthodox teachings.[3]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 inDunhuang texts and grottoes.[4][5]
