法華玄論 7.20

7.20

第五明本迹。一往八譬皆是迹中事耳。如來久已成佛，昔示同沙彌為說大乘，乃至今日中止一城，亦是方便成佛。是以八譬皆為迹也。但父子相見都有二本二迹：一者法身見諸菩薩大機已成，故示為舍那以化之，中止一城、家業不廢即其事也。二者舍那成道時，見諸子唯有小機無有大機，故垂為釋迦以化之，脫珍御服著弊垢衣即其事也。

Fifth is explaining the original and the trace. At first glance, all eight parables are matters within the trace. The Tathāgata attained buddhahood long ago; in the past, he manifested as a novice to preach the Mahāyāna, and down to stopping at a city midway today, this too is attaining buddhahood through skillful means. Therefore, all eight parables belong to the trace. However, the father and son seeing each other has two originals and two traces. First, the dharmakāya saw that the great spiritual capacity of the bodhisattvas had already matured, and thus manifested as Rocana to convert them; stopping midway at a city and not abandoning the family business are this very matter. Second, when Rocana attained awakening, he saw that the sons had only small spiritual capacity and no great spiritual capacity, and thus descended as Śākyamuni to convert them; taking off his fine royal garments and donning soiled, ragged clothes is this very matter.
