本願藥師經古迹 2.13

2.13

述曰：此即釋難門。於中有五：一難、二決、三徵、四解、五結。決意者，九種橫死皆不定業，宿業相似等流果故、若有助福得延長故。言終不能得者，夫殺生短命、食肉病多，而斷他命延己壽乎？得病雖輕，損滅壽業、橫死入獄，此中意也。結意者，若不延命，屬琰魔故，文相可知。

The commentary says: This is the section on resolving objections. In it there are five parts: first, the objection; second, the determination; third, the interrogation; fourth, the explanation; and fifth, the conclusion. The meaning of the determination is that the nine kinds of untimely death are all indeterminate karma, being the fruit of similarity and uniform outflow of past karma, and because if one has auxiliary merit, it can be prolonged. As for the statement 'in the end they cannot attain it': indeed, killing living beings causes short life spans, and eating meat causes much sickness; how then could cutting off the life of others prolong one's own life? Although the illness contracted is slight, it destroys the karma for life span, causing untimely death and entry into hell—this is the meaning here. As for the meaning of the conclusion: if life is not prolonged, one falls under the jurisdiction of Yama; the textual phrasing may be understood from this.
