7.378

初審問中，彼已自知，如問答訖。種姓根行彼不自知，以難知故，須更依言論所作。知他心智而求察之。基云：初一因緣尋求四處於利根人，更依下三因緣尋求三處所於鈍根人。何以得知者，下發生三因緣尋求三處所中，自生起所以，其驗三乘種中，不言聞三乘法而雨淚等者，此且據決定性人。

In the first, investigation, the person already knows oneself, as the questions and answers conclude. Lineage, faculties, and conduct the person does not know oneself; because they are difficult to know, one must further rely on verbal communication, actions, and knowledge of the minds of others to investigate and examine them. Ji says: The first condition of seeking the four grounds is for people of sharp faculties; further relying on the lower three conditions to seek the three grounds is for people of dull faculties. How is this known? In what follows, in generating the three conditions to seek the three grounds, the rationale naturally arises. In examining the lineage of the three vehicles, the omission of 'hearing the Dharma of the three vehicles and shedding tears, and so forth' is for the time being based on persons of determinate disposition.
