佛遺教經論疏節要 1.273

1.273

Those dragged by desire love forms and crave sounds without knowing where to stop; since they have no self-benefit, how could they pity others? One who is content has two benefits: first, not being dragged along by the five desires is self-benefit; second, being able to pity others is benefiting others. Since the mind pities, one will certainly instruct them. Laozi says: “The unvirtuous person is the resource for the virtuous person.”
