question:  What happened to the Sand God's race?
context: The sand-thing was powerful, lonely and strange. He touched the pencil-line scar behind his ear where the cylinder was buried, marveling at the power stored there, power to fling him from earth to this fourth planet of the Centaurian system in an instant. A gray, funnel-shaped cloud of dust stood off to his left. He was here and Earth was somewhere up there. He was here to investigate, to determine if this planet was capable of supporting life. He examined the wind devil as closely as he dared, but it was composed only of grains of sand. But then, how could a group of loosely spaced grains of sand possibly have a nervous system? He became so absorbed in doing this that he failed to notice how the wind devil drew closer and closer, but when he inhaled the first grains of sand, the realization of what was happening dawned with a flash of fear. From one angle they were animals, from another birds, from a third they were vaguely humanoid creatures, glowering at him with primitive ferocity. These creatures were not only humanoid, but definitely human, although more slight of build than earth people. The men were dark-skinned, the women somewhat lighter, with long flowing hair, wide lips and a beauty that was utterly sensual. But up to now the tube and the chain was the only evidence of an advanced technology, unless the ancient inscriptions in the stone wall of the pool, and the statues lining the wall were evidences. There, at the cavern entrance, the wind devil writhed and undulated in a brilliant harmony of colors. It came from the ceiling, the floor, the walls, the steaming pool. It is impossible to move a physical body from one place to another by a mere thought and a tiny instrument, yet you have done so. When they arrived on this planet I attempted to explain that I was not a God, but the primitive is not deeply buried in them. These are the undesirables, the incorrigibles, the nonconformists from the sixth planet.
output:  The Sand God's race learned how to separate the mind from the body. They set a date to leave their bodies together. The Sand God found himself alone after the experience.
