Rite Expiatis §26

²⁶ We must speak also of the "beauty and cleanliness of purity" which the Seraphic Father "loved singularly," of that chastity of soul and body which he kept and defended even to the maceration of his own flesh. We have already seen that as a young man, although gay and fashionable, he abhorred everything sinful, even in word. When later on he cast aside the vain pleasures of this world, he began to repress the demands of his senses with great severity. Thus at times when he found himself moved or likely to be influenced by sensual feeling, he did not hesitate to throw himself into a bush of thorns or, in the very depths of winter, to plunge into the icy waters of a stream.
