How does Toni Morrison use imagery in The Bluest Eye?

Imagery:

“All of our waste which we dumped on her and which she absorbed. And all of our beauty, which was hers first and which she gave to us. All of us--all who knew her--felt so wholesome after we cleaned ourselves on her. We were so beautiful when we stood astride her ugliness. Her simplicity decorated us, her guilt sanctified us, her pain made us glow with health, her awkwardness made us think we had a sense of humor. Her inarticulateness made us believe we were eloquent. Her poverty kept us generous. Even her waking dreams we used--to silence our own nightmares. And she let us, and thereby deserved our contempt. We honed our egos on her, padded our characters with her frailty, and yawned in the fantasy of our strength."

“Sunk in the grass of an empty lot on a spring Saturday, I split the stems of milkweed and thought about ants and peach pits and death and where the world went when I closed my eyes.”
