When this mountain monk
[I, Dôgen] was in Song
The duties of the cook over the course of a single day and night [are as follows].
First, following the midday meal, go to the offices of the prior and comptroller and get the ingredients for the next day's meals: rice, vegetables, and so on. Having received them, protect and be frugal with them, as if they were your own eyes. Chan Master Yong of Baoning [Monastery] said, "Protect and be frugal with monastery property, which is [like] your own eyes." Respect and value them as if they were ingredients for an imperial repast. These cautions apply to fresh and cooked things alike.
