'Furthermore, by wisdom born of hearing or by the divine eye, one sees breath-draining worms: out of anger, they eat the brain and make holes, causing either throat pain or throat obstruction, giving rise to the agony of death. These breath-draining worms, together with all the other worms in the throat, create turmoil and cause various pains and afflictions. These breath-draining worms are constantly covered by saliva; they are short and small, having faces and feet.'
