“The stress of being restrained for a long time can cause major gastrointestinal bleeding and ulcerization, but if the animal has the opportunity to bite something during the stress (signifying its ability to fight back and the possibility of escape) it can avoid the stress ulcers.”
― Raymond Peat

“Give not thyself up, then, to fire, lest it invert thee, deaden thee; as for the time it did me. There is a wisdom that is woe; but there is a woe that is madness. And there is a Catskill eagle in some souls that can alike dive down into the blackest gorges, and soar out of them again and become invisible in the sunny spaces. And even if he for ever flies within the gorge, that gorge is in the mountains; so that even in his lowest swoop the mountain eagle is still higher than other birds upon the plain, even though they soar.”
― Herman Melville, Moby-Dick or, The Whale

“Long is the way and hard, that out of Hell leads up to light.”
― John Milton, Paradise Lost
