a bodhisattva is an enlightened one who does not yet enter into Nirvana in order to teach the rest of us how to become enlightened ourselves.

I think the cherry blossoms teach us about the impermanence of this world, of how fleeting youth, beauty, and life on this earth in general is. I think we should take a lesson from the cherry tree and appreciate what we have, our loved ones, our own health and youth and not take them for granted because like the cherry blossoms, they will not last forever.
