How is the power of nature presented in poem kamikaze?

The poem presents natural elements such as cherry blossoms as metaphors for life: cherry trees that will soon die are just as beautiful because that transience, the fact that "they know this night of beauty is their very final bloom,'' makes that bloom much more beautiful and profound and therefore meaningful. This can relate specifically to a Kamikaze warrior's mindset -- to the idea that it is noble and virtuous to give one's life for something.
