From a style standpoint, I think you're better served sticking closer to the literal. Between the 2: "when trees in the woods grow tall, the wind blows them away".
I assumed "tallest tree catches the wind" was a rephrasing. I suggested it as an alternative because it's short.
I like the original "when trees in the woods grow tall, the wind blows them away" because it sounds intentionally verbose which is appropriate from the obviously educated sect master. And it has the literature reference which I really appreciate as a reader.
