Abu al-Ala al-Maarri, The Diwan of Abu'l-Ala
“ He tells us how the poet once recited verses in the presence of some people, and how one of them was a philosopher who said, "This man will not live long, for I have seen in him a sharpness of wit and penetration and intelligence. From this I know that the mind will consume the body, even as a sword of Indian steel eats through its scabbard." ”
