肇論新疏 2.246

2.246

履宜者，謂履踐道候相宜順也。思業，謂禪思行業。乾，健也，易初卦云「終日乾乾」，是以建德匪懈，曉夜勤勤。予近稟　灌頂上師著思吉剜卜，元言「法救」，行道精健，兢兢宵夕，學廣德高，叔世一人也。自非正歎，謂遠公如斯乾乾，蓋神智證理，即道之用潛注流行，故能爾爾。過順者，孔子自謂六十而耳順，今謂遠公六旬已上人也。所以下，劉復自敘。意云：謂遠德高廣，所以托身慰心亦深，恩大難答，致令仰德報謝其路尤絕。

"Maintained appropriate bodily conditions" means that his bodily health in practicing the Way is suitable and smooth. "Contemplative practice" refers to dhyāna contemplation and conduct in the practice. "Qian" (乾) means strong; the first hexagram of the Yijing says "diligent all day long," which is why he establishes virtue without flagging, industrious morning and night. I recently received instruction from the Abhiṣeka Guru Choeskyi Gyalpo, whose original language meant "Dharmatrāta"; his practice of the Way was refined and vigorous, careful day and night, of extensive learning and high virtue—the singular man of this degenerate age. "Were it not" is direct praise, meaning that Master Yuan is so diligent day and night because spiritual wisdom realizes principle, which is the function of the Way flowing secretly and smoothly; hence he can be like this. "Past the age of compliance" refers to Confucius saying of himself that at sixty his ear was attuned to compliance; here it means Master Yuan is a man over sixty years old. From "Therefore" onward, Liu again relates his own feelings. The meaning is: because Master Yuan's virtue is lofty and broad, Liu's reliant comfort of mind in entrusting himself to him is also deep; the kindness is vast and difficult to repay, which renders any path of looking up to his virtue to express gratitude all the more cut off.
