 Gaṅgeśa:  We answer. If we had to imagine that the word ‘Gaṅgā’ is used (as you claim) for the thousands of things that could be indicated by using the word for such a thing as a bank, then in order to understand a usage we would have to be familiar with another conventional practice of older persons (who have taught us the conventions of language) in each case among all the innumerable things that could be indicated. And so this view is uneconomical, and it is not borne out by experience.
