詳曰：二皆有理，且依後釋。如於人中起上界業，業屬上故。又人中業為彼遠緣亦應無失，如因欲善得上定故，若依前釋闕定異因。

Critical assessment: Both are reasonable; for now, rely on the latter explanation. Just as when karma of higher realms is produced among humans, the karma belongs to the higher [realm]. Furthermore, there should be no error in human karma acting as a distant condition for that, just as attainment of higher concentration occurs due to wholesome [actions] in desire; if one relies on the former explanation, it lacks a determinative differentiating cause.
