Even hearers and solitary realizers, who accomplish only their own welfare, strive as if putting out a fire on their heads. Seeing this, taking up diligent effort — the source of good qualities — for the sake of all beings is the Bodhisattvas’ practice.
A bodhisattva’s practice is to exert joyful perseverance,
the source of good qualities for the purposes of all wandering beings,
Since we can see that even shravakas and pratyekabuddhas,
Who would accomplish only their own purposes,
have such perseverance
That they would turn from a fire that has broken out on their heads.
