唯識二十論述記 1.136

1.136

Commentary: Previously, "and the like" was explained as matters other than excrement and pus. Now this explains "and the like" as right upon the pus and so forth, seeing sentient beings holding swords and clubs, warding off the hungry ghosts and guarding the pus and so forth, not allowing them to obtain food. Ghosts, due to evil karma, are profoundly starved and thirsty; even if they see pus, they run hoping to obtain it. But various sentient beings ward them off and prevent them from eating; they all see this together, not just one alone seeing it. Therefore the simile is established.
