2.82

Next, in resolving the objection: That text says, 'Abridged, there are eighty-four thousand; extensive, there are immeasurable and boundless.' Now, contrasted with the five hundred above, eighty-four thousand is provisionally taken as extensive; looking toward the immeasurable below, it turns out to still be an abridgment. Since there is no fixed number, one knows that the statement 'five hundred' is not false.
