parag. 3

"What you do is live life. What happens, happens whether you consciously invite it or not. What you do now, this you have a say about. In effect, you paddle your own canoe wherever it takes you. You are not helpless, however. You ride downstream, and it is the ride of your life. Or you ride upstream. Or you bobble around in life, and life is the bobble of your life. You do bobble on the surface. This is life. And yet life is a big blooming amaryllis. Life grows. Let life grow on you.

I am quite confused with this play of the noun and the verb "bobble" in "Or you bobble around in life, and life is the bobble of your life. You do bobble on the surface." There are so many different meanings of "bobble". Can you help me out?

Thanks
