仁王護國般若波羅蜜多經疏 1.48

1.48

Question: Why is it necessary to set aside the specific and collectively say "have I heard"? Answer: If one did not say "I" but merely said "the ear heard", the ear applies to all, so whose ear heard? Furthermore, at the time of hearing, the faculty, object, space, attention, discrimination, defiled and pure seeds, together with the fundamental support—if each and every one were fully set forth, it would become cumbersome and broad. If one stated only one, the meaning and function would not be comprehensive; therefore, setting aside the specific, it is collectively said "have I heard".
