仁王經疏 3.301

3.301

釋曰：第二、顯地別行。文別有三：一行四無畏、二辨除障、三入位分齊。就地數中，文別有二：初總標四數、後次第別釋。此即初也。謂第五地依順道忍起四無畏，於外四難心無怯懼，故名無畏。

Explanation: Second, showing the distinct practice of the bhūmi. The text has three parts: first, practicing the four fearlessnesses; second, distinguishing the elimination of hindrances; third, the limit of entering the rank. Concerning the enumeration of the bhūmi, the text has two parts: first, generally marking the number four; and next, distinguishing and explaining them in sequence. This is the first. It means that the fifth bhūmi, relying on the patience of accord with the path, gives rise to the four fearlessnesses; before the four external challenges, the mind has no fear or timidity, hence they are called 'fearlessnesses'.
