If you penetrate through the fourth into the spiritual world, you will have a strange experience. Although no new tones appear from any direction, those that have come before, when you were experiencing the third, will live lightly in the soul as memories. And you will find that in continuing to live with these tone memories they perpetually take on a fresh colouring; at one time they become as bright and cheerful as can be, at other times they descend to the utmost sadness; now they are as bright as day, now they sink down to the silence of the grave. The modulating of the voice, the way the sound ascends and descends; in short, the whole mood of a tonal creation will have its origin along this path, from these sound memories.
The fifth will produce experiences that are more subjective, that work to stimulate and enrich the life of the soul. It is like a magic wand that conjures up the secrets of the sound world yonder, out of unfathomable depths.
