Arcana Coelestia #10464
10464. 'And ground it up till it was powder' means the hellish falsity resulting from it. This is clear from the meaning of 'grinding up into powder', or into the tiniest parts, as producing falsity out of hellish delight, thus producing hellish falsity. The fact that 'grinding up', when it has reference to what is evil, has this meaning, becomes clear from what has been shown in 4335, 9995(end), 10303.
Revelation 18:21-22
21
A mighty angel took up a stone like a great millstone and cast it into the sea, saying, "Thus with violence will Babylon, the great city, be thrown down, and will be found no more at all.
22
The voice of harpists, minstrels, flute players, and trumpeters will be heard no more at all in you. No craftsman, of whatever craft, will be found any more at all in you. The sound of a mill will be heard no more at all in you.
