第一證中集起心者，又解所集種、處起生法，因故名為心，破色不相應及心所中，亦應有非染淨種所集起心。略無之也。

Regarding the 'mind that accumulates and generates' in the first proof, it is also explained that because it is the cause from which accumulated seeds and bases generate dharmas, it is named 'mind' (citta). In refuting matter, the non-associated [dharmas], and mental factors, there should also be the mind that is accumulated and generated by seeds that are neither defiled nor pure. It is omitted for brevity.
