How does Li-Young Lee use imagery in The Weight of Sweetness?

"The Weight of Sweetness" proceeds from abstract statements to concrete images. Abstractions are ideas, and are rooted in the intellect. Concrete images are things which can be seen: blue hair, spilled milk, etc. Lee begins his poems by making connections among abstractions such as wisdom, sadness, joy, gravity, and sweetness. He then uses concrete imagery such as peaches to illustrate these connections.
