Now Euxenus realized that he was attached to a lofty ideal, and asked him at what point he would begin it. Apollonius answered: "At the point at which physicians begin, for they, by purging the bowels of their patients prevent some from being ill at all, and heal others."

And of wine he said that it was a clean drink because it is yielded to men by so well-domesticated a plant as the vine; but he declared that it endangered the mental balance and system and darkened, as with mud, the ether which is in the soul. After then having thus purged his interior, he took to walking without shoes by way of adornment and clad himself in linen raiment, declining to wear any animal product.
