Considering the fact that it was created by spirits in a purely spiritual world, I doubt it's a living thing. It clearly has a mind of some sort, detecting people's desires. Unless it is complicated enough to delve into their brains and sense their brain waves. But anything beyond that is pure speculation. We'll probably find out what it is eventually.
