When various spiritual writings make reference to a "glorified body," it is this new kind of form that is being referred to. In order to understand this, one needs to consider the spectrum of existence. We each occupy a spectrum of reality that spans from these dense physical bodies up through many levels — each one of a finer substance than the one below it — to a level where we are pure consciousness and light. If you pass white light through a prism, it will spread out into bands of different colored light. A rainbow exhibits these colors when sunlight passes through a mist of water droplets, each of which acts as a tiny prism that splits the light into those bands of color with which we are so familiar.
