Those musical instruments respond which have the same attunement of vibration, as it were; if the state of vibration, which they call "man-vibration", should be changed, no longer would men be seen here; the whole "man-universe" would vanish, and instead of that, other scenery would come before us, perhaps gods and the god-universe, or perhaps, for the wicked man, devils and the diabolic world; but all would be only different views of the one universe. It is this universe which, from the human plane, is seen as the earth, the sun, the moon, the stars, and all such things — it is this very universe which, seen from the plane of wickedness, appears as a place of punishment. And this very universe is seen as heaven by those who want to see it as heaven. Those who have been dreaming of going to a God who is sitting on a throne, and of standing there praising Him all their lives, when they die, will simply see a vision of what they have in their minds; this very universe will simply change into a vast heaven, with all sorts of winged beings flying about and a God sitting on a throne. These heavens are all of man's own making. So what the dualist says is true, says the Advaitin, but it is all simply of his own making. These spheres and devils and gods and reincarnations and transmigrations are all mythology; so also is this human life.
