(The Master further rewarded him with a robe. Fangbian took the robe and divided it into three: one to drape over the sculpted image, one kept for himself, and one wrapped in palm bark and buried in the ground. He made a vow, saying, "Whoever finds this robe in the future will be my rebirth, who will dwell as abbot here and rebuild the halls." In the eighth year of the Jiayou era of the Song, a monk named Weixian, while repairing the hall and excavating the ground, obtained the robe looking like new. The image is at Gaoquan Temple, and prayers to it are always answered.)
