The five ‘primary’ elements (5th space) are the intrinsic radiance of the spectrum of light spontaneously emanating from the crystal prism of pristine awareness. Projected externally these lights are reflected in the five lights of external objects (sights, sounds, smells, tastes and tactile sensations), and thus are like external reflections of the lights projected by the intrinsic glow of the crystal (pristine awareness). When these external reflections are concretized in the process of perception, different configurations of the five elements.... mere ‘sediments’ of the lights.... come to be misconstrued as matter and energy, worlds and life forms, habitats and inhabitants. Yet throughout this confusion, they have intrinsically remained pure-light potency, though fractured as impure vibrations of the five elements. Longchenpa
