I felt a sense of horror while looking at it. But if it had been the other way around - ie, a rodent eating a toad - it would not have had as much emotional impact, because the little rat-like creature is cute, and the toad is,,,horrible and ugly.
The lesson? Try to avoid being reborn as an animal, where this kind of miserable end is commonplace, maybe?
Then the Blessed One, picking up a tiny bit of dust with the tip of his fingernail, said to the monk, "There isn't even this much form...feeling...
perception...fabrications...consciousness that is constant, lasting, eternal, not subject to change, that will stay just as it is as long as eternity."
