Their whole moral is based upon the principle of harmlessness, and their priests cause still less harm than the other followers of Jainism. In order to be least harmful, they avoid wearing shoes, avoiding two harms thereby: one being that the leather which is used to make shoes causes the death of so many lives, and the other that by walking with shoes one crushes and kills more lives than by walking barefoot. Some among them are seen with a little piece of cloth tied over their lips, for by walking with open mouth, as so many do, so many small lives are drawn into the mouth. A]so there is another reason, that is, to keep as much as possible from talking. Mostly inharmony and a great many other faults are caused by talkativeness, which is often needless.
