大般涅槃經義記 1.193

1.193

第三請中，「如飢無吐」，立喻請佛。佛常思化，如世飢人願莫捨我，名不變吐。「願使」已下，約喻求佛，願如飢人，莫捨我等，入涅槃去。

In the third entreaty, "Like a hungry person who does not vomit" establishes an analogy to entreat the Buddha. The Buddha constantly contemplates transformation, like a hungry person in the world; wishing that he not abandon us is called "not vomiting." From "May you cause..." downward, he seeks the Buddha in reference to the analogy, wishing that like the hungry person, he not abandon us and enter nirvāṇa.
