5.75

As the Da yijiao jing says: When a monk wishes to eat, he should burn incense for the donor and chant three hymns, praising the giving of delicious food that can be eaten. Furthermore, following the instruction of the elder monk, the practitioners each go out to wash their hands and rinse their mouths, and having done so, each returns to sit in his seat. Each recites a verse, rising in sequential order, and must not jump out of order.
