On the verge of his own death, Bernard has a vision of the order in the universe, but he’s only able to glimpse it incompletely from his mortal vantage point. The book’s sense that there’s order to be found in the world, especially in the cycles of life, doesn’t prevent an individual’s experience from being painful or confusing at times. When Bernard’s book falls from his hand, it symbolically points toward his death—with the end of his life approaching, there’s no longer any need to store up inspirations for his someday book. But it can also suggest that the notebook has become redundant, since Bernard has grasped (however incompletely) the truth that the force that propels life forward (represented here by the power of the waves) will carry on long after he (and, by extension, even readers) dies. And thus, he faces his mortality not with fear, but with hope.
