so take the lively air,
And, lovely, learn by going where to go (14-15)
Just as the tree got taken by light, you now get to take the air. Breathe in, live. You can become something more, something lovely, maybe, learning by the act of going where you need to go. The line has lost the compulsion of fate. With the knowledge of your own mortality, your limits, you’re free now. You can go where you want.
