處處經云。佛言中後不食。有五福。一少淫。二少睡。三得一心。四無下風。五身得安樂。亦不作病。是故。沙門知福不食。

The Chuchu jing states: The Buddha said that not eating after noon yields five blessings: first, less lust; second, less sleepiness; third, attaining singleness of mind; fourth, no flatulence; fifth, the body attains peace and ease, nor does it generate sickness. Therefore, śramaṇas, knowing the blessings, do not eat [after noon].
