瑜伽師地論略纂 12.38

12.38

論解能得忍陀羅尼中云「成熟自然堅固因行」者，謂在地前，是忍云因，不可動故，名不動因行。「具足妙慧」者，即成熟趣出世之妙慧也，或於不動因行中具足妙慧。　「獨處空閑」者，言住處也。　「寂無言說」，離言諠雜。　「曾無有物」者，其意省事，無餘資具物。　「見路而行」者，謂不應行，必明相生時方行，故言見路而行。又所行之處必見正路，不染非過，非過名野處。正理必名路，依正理行，名見路行。「知量而食」等，可知。

In the treatise's explanation of the dhāraṇī capable of obtaining patience, it says: "Ripening natural and firm causal practice": this means that prior to the bhūmis, this patience is called the cause; because it is unshakeable, it is called "unshakeable causal practice." "Endowed with wondrous wisdom": this means ripening the wondrous wisdom that tends toward the supramundane; or, being endowed with wondrous wisdom within the unshakeable causal practice. "Dwelling alone in a secluded and quiet place": this speaks of the dwelling place. "Silent and free from speech": free from verbal clamor. "Having never possessed possessions": this means minimizing affairs and possessing no extraneous material requisites. "Walking while seeing the road": this means when one should not walk, one only walks when the signs of dawn appear, hence it says "walking while seeing the road." Moreover, the place where one walks must show the correct path, unblemished by faults; absence of faults is called a wilderness. Correct principle must be called the "road"; walking in accordance with correct principle is called "walking while seeing the road." "Eating with moderation" and so on can be understood.
