। ॥ ६८४ ॥
In plain words
Inside, outside — look anywhere on it: what you see is clay. Not a pot, not a lid, not one item of the whole set is anything apart from clay. And that thing with the neck and the belly and the rim, the thing you call a pot — don't call it that. This too is clay, and nothing else.
Close to the Sanskrit
Inside and outside also, clay alone is seen; nothing whatever, pot and the rest, is separate from clay. That pot which possesses a neck and the other features — that is not to be spoken of in this way; and this is clay alone, not another thing.
