尼羯磨 3.41

3.41

自今已去，與諸比丘尼結如草覆地滅諍法，應如是說如草覆地。（云何草覆地？此罪更不說罪名、罪種懺悔者是。）

From this day forth, when determining the settlement of disputes by covering over with grass for the bhikṣuṇīs, one should speak in this way of covering over with grass. (What is covering over with grass? It is when one does not further declare the names or classes of the offences to confess them.)
