Antony, however, according to his custom, returned alone to his own cell, increased his discipline, and sighed daily as he thought of the mansions in Heaven, having his desire fixed on them, and pondering over the shortness of man's life. And he used to eat and sleep, and go about all other bodily necessities with shame when he thought of the spiritual faculties of the soul. So often, when about to eat with any other hermits, recollecting the spiritual food, he begged to be excused, and departed far off from them, deeming it a matter for shame if he should be seen eating by others.
