In the book a step from heaven what does rain symbolize? What does the grass symbolize? And what does heaven symbolize?

Harabugi teaches Young Ju about Heaven and the power of prayer. She tells Young Ju that everyone who prays and loves God will go to Heaven, and that her Harabugi is waiting for her there. As a pre-school immigrant, Young Ju confuses America with Heaven. She is severely disappointed when she arrives in her new country to find that is nothing like Heaven.
