供給中，初科。《五分》唯開自煮。《五百問》亦然，七日一受，更開過中失受，惡觸不受。先淨，謂令淨人火淨。下指《寶梁》，彼云：乞食比丘，或病不能乞食，當自伏心云：我獨無侶，一身出家，法是我伴等。《習禪經》今藏錄不出。

Under Providing Provisions, the first section: The Mahīśāsaka-vinaya only allows cooking for oneself. The Five Hundred Questions is also like this: receiving [food] once every seven days, and further making an exception that receiving is lost after midday, and evil touch is not received. "Purifying first" means having a pure person purify it with fire. Below it points to the Ratnarāśi, which says: "A bhikṣu who begs for food, if sick and unable to beg for food, should subdue his own mind, saying: 'I am alone without a companion, having left home by myself; the Dharma is my companion,' and so forth." The Dhyāna Practice Sūtra is not listed in the current canon catalogue.
