How gluttonous desires can be overcome.
First then we must trample under foot gluttonous desires, and to this end the mind must be reduced not only by fasting, but also by vigils, by reading, and by frequent compunction of heart for those things in which perhaps it recollects that it has been deceived or overcome, sighing at one time with horror at sin, at another time inflamed with the desire of perfection and saintliness: until it is fully occupied and possessed by such cares and meditations, and recognizes the participation of food to be not so much a concession to pleasure, as a burden laid upon it; and considers it to be rather a necessity for the body than anything desirable for the soul. And, preserved by this zeal of mind and continual compunction, we shall beat down the wantonness of the flesh (which becomes more proud and haughty by being fomented with food) and its dangerous incitement, and so by the copiousness of our tears and the weeping of our heart we shall succeed in extinguishing the fiery furnace of our body, which is kindled by the Babylonish king 838 who continually furnishes us with opportunities for sin, and vices with which we burn more fiercely, instead of naphtha and pitch—until, through the grace of God, instilled like dew by His Spirit in our hearts, the heats of fleshly lusts can be altogether deadened. This then is our first contest, this is as it were our first trial in the Olympic games, to extinguish the desires of the palate and the belly by the longing for perfection. On which account we must not only trample down all unnecessary desire for food by the contemplation of the virtues, but also must take what is necessary for the support of nature, not without anxiety of heart, as if it were opposed to chastity. And so at length we may enter on the course of our life, so that there may be no time in which we feel that we are recalled from our spiritual studies, further than when we are obliged by the weakness of the body to descend for the needful care of it. And when we are subjected to this necessity—of attending to the wants of life rather than the desires, of the soul—we should hasten to withdraw as quickly as possible from it, as if it kept us back from really health-giving studies. For we cannot possibly scorn the gratification of food presented to us, unless the mind is fixed on the contemplation of divine things, and is the rather p. 239 entranced with the love of virtue and the delight of things celestial. And so a man will despise all things present as transitory, when he has securely fixed his mental gaze on, those things which are immovable and eternal, and already contemplates in heart—though still in the flesh—the blessedness of his future life.
