Some proverbs are stranger than others, or more potent both in their meaning and that they may require more thought to work out. And some are strange and potent.
Still, one generally does not expect a talking wild boar called the Lord of Wisdom to be the one to give it. Then again, Patricia A. McKillip seldom does what one expects.

"The giant Grof was hit in one eye by a stone, and that eye turned inward so that it looked into his mind, and he died of what he saw there."
