From “The Story of El-ahrairah and the Black Rabbit of Inlé” (chapter 31) in Watership Down: A Novel by Richard Adams:
El-ahrairah went along the hedgerow to the wood and sat alone under a nut bush, looking out across the fields. As the light began to fail, he suddenly realized that Lord Frith was close beside him, among the leaves.
“Are you angry, El-ahrairah?” asked Lord Frith.
“No, my lord,” replied El-ahrairah, “I am not angry. But I have learned that with creatures one loves, suffering is not the only thing for which one may pity them. A rabbit who does not know where a gift has made him safe is poorer than a slug, even though he may think otherwise himself.”
“Wisdom is found on the desolate hillside, El-ahrairah, where none comes to feed, and the stony bank where the rabbit scratches a hole in vain.”
