俱舍論記 4.3

4.3

「今應思擇至決定俱生」者，此下當品大文第二明俱生法，即約俱生辨用。就中，一正明俱起、二廣辨差別。就初門中，一明色法俱生、二明四品同起。此下第一明色法俱生，將明問起。就中，一問、二答，此即問也。今應思擇一切有為如體相不同，生時亦各各別異而生，為有諸法決定俱生。又解：總為一問。一切有為如體相不同，其生亦各異。於此異體別生有為法中，為有諸法決定俱生。

Regarding '[The question] now to be investigated is [...] they definitely arise together': below this, the second major section of this chapter explains co-arising phenomena (sahabhū-dharma), namely analyzing functions with respect to co-arising. Within it, [there are two parts]: first, directly explaining the co-arising of material phenomena (rūpa-dharma); second, extensively analyzing the distinctions. Within the first section, [there are two parts]: first, explaining the co-arising of material phenomena; second, explaining the simultaneous arising of the four classes. Below this is the first [part], explaining the co-arising of material phenomena, which introduces the topic by raising a question. Within it, [there are]: first, the question; second, the answer. This is the question. We should now investigate whether all conditioned phenomena (saṃskṛta), just as their substantial characteristics are not identical, also arise separately and distinctly from one another when they arise, or whether there are phenomena that definitely arise together. Another explanation: it forms a single comprehensive question. All conditioned phenomena, just as their substantial characteristics are not identical, also arise distinctly from one another. Among these conditioned phenomena of distinct substances and separate arisings, are there phenomena that definitely arise together?
