If sweet water flows in all the rivers

If sweet water flows in all the rivers, from where does the ocean take its salt?

How do the seasons know that they should change their costumes?

Why, so listless in winter, are they so passionate after?

And how do the roots know they should rise up toward the sun?

And later, wave at the air with such flowers and colors?

Is it always the same Spring who reprises her role, forever?
