That would be the "silent as a forest" part of the book. The idea is that a soldier should be fast like the wind (the coursing river), fierce as the fire (obvious here), and the force of the mountain (the great typhoon), while still being as silent and stealthy as the forest (the darkside of the moon). I didn't notice it until I remembered exactly what those lines reminded me of.
