With the music of the absolute the bass, the undertone, is going on continuously, but on the surface and under the various keys of all the instruments of nature's music the undertone is hidden and subdued. Every being with life comes to the surface and again returns whence it came, as each note has its return to the ocean of sound. The undertone of this existence is the loudest and the softest, the highest and the lowest. It overwhelms all instruments of soft or loud, high or low tone, until all gradually merge in it. This undertone always is, and always will be.
