汾陽無德禪師語錄 2.52

2.52

龍潭在俗時，常供餅十枚上天皇，皇食已每留一餅，與之曰：「惠汝以蔭子孫。」師忽訝之問曰：「餅是某甲將來，何以返云惠汝。」皇曰：「是汝持來，復汝何咎。」師因悟，遂投出家。

When Longtan was still a layman, he regularly offered ten cakes to Tianhuang. Whenever Tianhuang finished eating, he would leave one cake and give it back to him, saying, "I bestow this upon you to shade your sons and grandsons." The Master suddenly wondered at this and asked, "The cake was brought by me; why do you turn around and say you bestow it upon me?" Tianhuang said, "It was brought by you; what fault is there in returning it to you?" The Master was enlightened because of this and subsequently left home [to become a monk].
