[St. Anthony said] that it was more fitting for young men to hold to the ascetic life with zeal and not to seek things that enervate the body, but rather to accustom it to labors, bearing in mind the apostle's words, "When I am weak, then I am strong." For he used to say that the nous of the soul is strong when the pleasures of the body are weak....
For a man's whole life is very short when measured by the ages to come; all our time is nothing compared to eternal life. In the world everything is sold at its value and an item is exchanged for its equivalent, but the promise of eternal life is bought for a trifle....
