Supposing a man were to collect all the grass, sticks, etc., in Jambudīpa, and after making sticks of various sizes were to impale on them all the creatures of the ocean, creatures of all sizes, even so a majority of the minute animals would remain free, being too small to be impaled. Even thus widespread is the ruin of things, yet from such widespread ruin will be saved those who have the gift of realizing the Four Noble Truths. S.v.441.
