瑜伽論記 19.186

19.186

言於自體上行於正行者，謂如善巧家長，於未成熟幼童者，自察是非捨非從是，如彼家長教彼幼童。家長喻菩薩行者，未成就幼童，喻諸德行未成。

Where it says 'practicing correct practice upon one's own body', it means: just as a skillful householder, regarding an immature young child, inspects right and wrong oneself, abandoning the wrong and following the right, just as that householder instructs that young child. The householder is a metaphor for the bodhisattva practitioner, and the immature young child is a metaphor for the virtues not yet completed.
