How does Robert Morgan use imagery in The Truest Pleasure?

Imagery:

"Anger is among the sweetest feelings people know. That's why they cherish it and feed it and remember it so long. Anger is like a tightening and sharpening of sight. It is the brightest angle from which to look at things."

"We was in no hurry because we knowed something would be give to us. I thought about the beans we had picked that day, and how beans get hard when they are ready to pick. You could pick beans just by the feel of them. With your fingers you could tell the pulses in a bean, and then count the beans into a basket."
