於中，初正出忍體，遍於一切等者，對有情能忍，後普於一切等者，對法能忍。由無染心，能悲愍故，能忍者，釋成忍義由貪染愛己身逢違即忿，故依無染心能有堪忍。由瞋無悲憐物遇違便怒，故依悲愍能有堪忍。

Herein, first it directly sets forth the essence of patience. 'Pervasive toward all, etc.' refers to being able to endure toward sentient beings; later, 'universal toward all, etc.' refers to being able to endure toward phenomena. 'Due to an undefiled mind, being able to be compassionate, one is able to endure' explains the meaning of patience: through defilement of greed one loves one's own body, and meeting adversity one immediately becomes indignant; therefore, based on an undefiled mind one is capable of endurance. Through anger one lacks compassion and pity for beings, and encountering adversity one becomes furious; therefore, based on compassion one is capable of endurance.
