Drinking the driven storm, the sturdy apple
Dances, between sky and earth, her spring-young leaves.
Knowing no purpose, knowing only season,
Her spring-young leaves, storm-driven, dapple
Earth and sky; all that my eye perceives
Dances. My eye drinks in the apple’s spring-
Young leaves, her dance that has no reason:
Only the storm, driving each dappled thing.

This poetic form is called san san, which means “three three” in Chinese (and is a term of art in the game Go). It rhymes as you see (a-b-c-a-b-d-c-d), and also repeats, three times, each of three terms or images; here, the driven storm; the spring-young leaves; the dance.

Here are a few more of these.
