大方廣佛華嚴經疏 52.26

52.26

大文第五「十種身業」下有五十門，答五十問，明十地位中行相。古德分四：初十二門，明十地中三業殊勝行，寄在初地；二從「十種勤修」下九門，明造修離障行，寄二三地；三從「十種離生道」下九門，明造修純熟行，寄在四地已上位；四從「十種足」下二十門，報相圓滿行，寄八地已上位。此釋猶稍近，文亦未盡理。今亦依次分配十地：初地十門，次八漸略，文勢爾故。謂二地六門，三四各五門，五二、六一、七八各三，九地二門，十地十三門，至文當知。

Fifth in the major section: below "ten kinds of bodily karma" there are fifty gates answering fifty questions, elucidating the aspects of practice in the stations of the ten stages. Ancient masters divided them into four: first, twelve gates elucidating the supreme practice of the three karmas in the ten stages, assigned to the first stage; second, nine gates from "ten kinds of diligent cultivation" onward, elucidating the practice of cultivating to leave obstacles behind, assigned to the second and third stages; third, nine gates from "ten kinds of ways to transcend worldly birth" onward, elucidating the practice of fully ripened cultivation, assigned to the stages from the fourth stage upward; fourth, twenty gates from "ten kinds of feet" onward, the practice of the full perfection of reward marks, assigned to the stages from the eighth stage upward. This explanation is somewhat close, yet its text still does not exhaust the principle. Here they are also distributed sequentially to the ten stages: ten gates for the first stage, with the next eight stages gradually abbreviated, because such is the textual momentum. That is, six gates for the second stage, five gates each for the third and fourth, two for the fifth, one for the sixth, three each for the seventh and eighth, two gates for the ninth stage, and thirteen gates for the tenth stage, which will be understood when reaching the text.
