"One who has profoundly internalized virtue is comparable to the infant. Wasps, scorpions, adders, and vipers do not sting or bite him. Fierce animals do not attack him. Birds of prey do not seize him."
This passage from verse 55 of the Daode Jing (translated by Richard John Lynn) is cited in Sam Crane's Daoist Thoughts On Newtown -- definitely worth a read.
