說無垢稱經疏 6.164

6.164

贊曰：此歎菩薩。忍種種勞倦者，利眾生時苦惱事也。勝希堅牢者，眾事惱亂，不退敗也。過外道等，名勝精進。世間難遇，名希有。不可退屈，名堅牢。不可思議，策勵深也。大悲精進，為物起也。此精進言，通上諸義：一勝、二希、三堅牢、四不思議、五大悲精進。

Commentary: This praises the bodhisattvas. 'Enduring various kinds of fatigue' refers to the painful and vexing matters when benefiting sentient beings. 'Superior, rare, and firm' means that although vexed and troubled by all kinds of affairs, they do not retreat or fail. Surpassing non-Buddhists and the like is called 'superior vigor'. Being rarely encountered in the world is called 'rare'. Being incapable of retreating or giving way is called 'firm'. 'Inconceivable' refers to their urging and striving being profound. 'Great compassion and vigor' is aroused for the sake of beings. The word 'vigor' applies across the preceding meanings: first, superior; second, rare; third, firm; fourth, inconceivable; and fifth, vigor of great compassion.
