1.201

「大德僧聽！我比丘為僧唱淨地處所。此僧伽藍內東廂厨院中，若諸果樹下，並作淨地。」

"May the venerable saṃgha listen! I, the bhikṣu, announce for the saṃgha the location of the pure ground: inside this saṃghārāma, within the kitchen courtyard of the eastern wing, and beneath the various fruit trees, are entirely made a pure ground."
