31. So that, if we are desirous of returning to those natures with which we formerly associated, we must endeavour to the utmost of our power to withdraw ourselves from sense and imagination, and the irrationality with which they are attended, and also from the passions which subsist about them, as far as the necessity of our condition in this life will permit. But such things as pertain to intellect should be distinctly arranged, procuring for it peace and quiet from the war with the irrational part; that we may not only be auditors of intellect and intelligibles, but may as much as possible enjoy the contemplation of them, and, being established in an incorporeal nature, may truly live through intellect; and not falsely in conjunction with things allied to bodies. We must therefore divest ourselves of our manifold garments, both of this visible and fleshly vestment, and of those with which we are internally clothed, and which are proximate to our cutaneous habiliments; and we must enter the stadium naked and unclothed, striving for [the most glorious of all prizes] the Olympia of the soul. The first thing, however, and without which we cannot contend, is to divest ourselves of our garments. But since of these some are external and others internal, thus also with respect to the denudation, one kind is through things which are apparent, but another through such as are more unapparent. Thus, for instance, not to eat, or not to receive what is offered to us, belongs to things which are immediately obvious; but not to desire is a thing more obscure; so that, together with deeds, we must also withdraw ourselves from an adhering affection and passion towards them. For what benefit shall we derive by abstaining from deeds, when at the same time we tenaciously adhere to the causes from which the deeds proceed? 32. But this departure [from sense, imagination, and irrationality,] may be effected by violence, and also by persuasion and by reason, through the wasting away, and, as it may be said, oblivion and death of the passions; which, indeed, is the best kind of departure, since it is accomplished without oppressing that from which we are divulsed. For, in sensibles, a divulsion by force is not effected without either a laceration of a part, or a vestige of avulsion. But this separation is introduced by a continual negligence of the passions. And this negligence is produced by an abstinence from those sensible perceptions which excite the passions, and by a persevering attention to intelligibles. And among these passions or perturbations, those which arise from food are to be enumerated.
