9.354

述曰：此即依前種子三義中第三正義答。未聞正法，但無漏種無始自成，不曾熏習令其增長，名本種姓。性者體也；姓者類也。謂本性來住此菩薩種子姓類差別，不由今有，名本性住種姓。三十五〈菩薩地〉云：無始法爾，六處殊勝，名本姓住種。正與此同，即種姓住。

The Commentary states: This answers in accordance with the third, correct doctrine among the previous three meanings of seeds. Before hearing the correct Dharma, the uncontaminated seeds are merely established of themselves from beginningless time, never having been perfumed to make them increase; this is called the original gotra. 'Xing' (nature) is substance; 'xing' (clan/lineage) is category. This means that from original nature, one abides in the distinction of this category of bodhisattva seeds, which does not exist only from the present; hence it is named the 'gotra residing in original nature' (prakṛtistha-gotra). Fascicle 35, the *Bodhisattvabhūmi*, states: 'Beginningless and naturally so, the excellence of the six sense-bases is named the seed residing in original nature.' This exactly agrees with this; it is precisely the abiding of the gotra.
