I would start up in a pious rage and cast out such thoughts by more strenuous prayer and still more strenuous fasting. But as my body grew accustomed to the discomforts to which it was subjected, my mind assumed a rebellious freedom that clogged the work of purification upon which I strove to engage it. My stomach out of its very emptiness conjured up evil visions to torment me in the night, and with these I vainly wrestled until I remembered the measures which Fra Gervasio told me that he had taken in like case. I had then the happy inspiration to have recourse to the hair-shirt, which hitherto I had dreaded. It would be towards the end of October, as the days were growing colder, that I first put on that armour against the shafts of Satan. It galled me horribly and fretted my tender flesh at almost every movement; but so at least, at the expense of the body, I won back to some peace of mind, and the flesh, being quelled and subdued, no longer interposed its evil humours to the purity I desired for my meditations. For upwards of a month, then, the mild torture of the goat's-hair cilice did the office I required of it. But towards December, my skin having grown tough and callous from the perpetual irritation, and inured to the fretting of the sharp hair, my mind once more began to wander mutinously. To check it again I put off the cilice, and with it all other undergarments, retaining no more clothing than just the rough brown monkish habit. Thus I exposed myself to the rigours of the weather, for it had grown very cold in those heights where I dwelt, and the snows were creeping nearer adown the mountain-side. I had seen the green of the valley turn to gold and then to flaming brown. I had seen the fire perish out of those autumnal tints, and with the falling of the leaves, a slow, grey, bald decrepitude covering the world. And to this had now succeeded chill wintry gales that howled and whistled through the logs of my wretched hut, whilst the western wind coming down over the frozen zone above cut into me like a knife's edge. And famished as I was I felt this coldness the more, and daily I grew leaner until there was little left of my erstwhile lusty vigour, and I was reduced to a parcel of bones held together in a bag of skin, so that it almost seemed that I must rattle as I walked. I suffered, and yet I was glad to suffer, and took a joy in my pain, thanking God for the grace of permitting me to endure it, since the greater the discomforts of my body, the more numbed became the pain of my mind, the more removed from me were the lures of longing with which Satan still did battle for my soul. In pain itself I seemed to find the nepenthes that others seek from pain; in suffering was my Lethean draught that brought the only oblivion that I craved.
