In fact, a careful reading of the Torah shows that it sees everything in the world as belonging to one of three primary domains: the good, the bad, and a third realm that's more difficult to define. In Halachah (Torah law) it's called "the optional" (reshut); in Kabbalah and Chassidism it's refered to as "the translucent husk" (kelipat nogah) or simply, "the undefined". Basically, in this third category a thing is not what it is, but what you make of it. It can be elevated to the realm of holy, or dragged down into the realm of the profane -- depending on what you do with it, what you use it for, even what you're thinking while you're involved with it.
