Flowers fall, while weeds flourish

So I'm reading Sit Down and Shut Up by Brad Warner, and on page 20 he quotes Dogen:

Flowers while loved fall, weeds while hated flourish.
Warner goes on to say "Whether we like or hate what life hands us, it is what it is and that's all it is."

I feel like I can stop reading right here, because this is really it, isn't it? It doesn't really matter that we love flowers if what we've got is a garden full of weeds. The universe doesn't give a rat's ass. It just presents what's there. Before I sound too depressed, I actually think this is an incredibly useful way to look at life. Our desires, our selves, are really irrelevant in the big scheme of things, yet we make them the central focus of our lives.
