論。云何修行至速離眾苦　述曰。此中即顯三種精進。於諸善事不退等者。被甲精進。如世被甲無退屈故。當念過去久遠等者。攝善精進。念昔虛苦令勤善故。自利利他速離苦者。利樂精進。欲脫他苦自精進故。

[Treatise:] How does one cultivate ... swiftly depart from all sufferings. [Exposition:] Here the three kinds of vigor are clarified. Not regressing in wholesome actions, etc., is armor-like vigor, because just as in the worldly realm one puts on armor and does not yield. Recalling the distant past, etc., is the vigor of gathering the wholesome, because by mindful awareness of past futile suffering one is made diligent in the wholesome. Benefiting oneself and benefiting others to swiftly depart from suffering is the vigor of benefiting and bringing joy, because wishing to liberate others from suffering, one is vigorous oneself.
