The following text is adapted from a story about a diver.

I hovered at the edge of the boat; I checked my oxygen tank; I looked down at the dark waves; the noise of the engine ceased; I could not see beneath the surface; and my mind seemed drawn from the noisy deck to that water expanded below me—a deep blue void absolved from the chaos of the world above.

As used in the text, what does the word "absolved" most nearly mean?
