仁王經疏 1.29

1.29

問曰：阿難如來成道日生，經二十年方為侍者，前所說經皆非親聞，如何諸經皆說我聞？答：依《報恩經》釋有三義：一者阿難從他諸天及諸比丘邊傳聞。二者佛入世俗心，令阿難知前所說經。三者前所說經佛重為說。佛善巧力故，於一法句中演無量法，能以無量法為一句義。佛粗示其端，阿難蓋已得知，速利強持力故。

Question: Ānanda was born on the day the Tathāgata achieved enlightenment, and twenty years passed before he became an attendant. The sūtras preached before that were not heard by him in person; how is it that all sūtras say “I have heard”? Answer: According to the explanation in the *Bao’en jing*, there are three points: First, Ānanda heard them transmitted from other devas and monks. Second, the Buddha entered a conventional state of mind to make Ānanda know the sūtras preached before. Third, the Buddha repeated for him the sūtras preached before. Through the Buddha’s power of skill-in-means, within a single Dharma phrase he expounded immeasurable dharmas, and could make immeasurable dharmas the meaning of a single phrase. The Buddha merely indicated their rough outline, and Ānanda had already come to understand them, due to the power of his swift, sharp, and strong retention.
