Recognitions

But as soon as day began to advance the dawn upon the retiring darkness, Peter having gone into the garden to pray, and returning thence and coming to us, by way of excuse for awaking and coming to us a little later than usual, said this: “Now that the spring-time has lengthened the day, of course the night is shorter; if, therefore, one desires to occupy some portion of the night in study, he must not keep the same hours for waking at all seasons, but should spend the same length of time in sleeping, whether the night be longer or shorter, and be exceedingly careful that he do not cut off from the period which he is wont to have for study, and so add to his sleep and lessen his time of keeping awake. And this also is to be observed, lest haply if sleep be interrupted while the food is still undigested, the undigested mass lead the mind, and by the exhalation of crude spirits render the inner sense confused and disturbed. It is right, therefore, that that part also be cherished with sufficient rest, so that, those things being sufficiently accomplished which are due to it, the body may be able in other things to render due service to the mind.”
