35 “I die daily,” says the Apostle. Better certainly is this saying than theirs who said that meditation on death was true philosophy, for they praised the study, he exercised the practice of death. And they acted for themselves only, but Paul, himself perfect, died not for his own weakness but for ours. But what is meditation on death but a kind of separation of body and soul, for death itself is defined as nothing else than the separation of body and soul? But this is in accordance with common opinion.
