c39.s1.13

Every phenomenon, it has been expressed, consists of a three-fold *arche*, intelligible Essence, Energy and Mass. In intimate union these enter into things as essential constitutive factors. The Essence of a thing (*sattva*) is that by which it manifests itself to intelligence, and nothing exists without such manifestation in the universe of consciousness But the Essence is only one of these moments. It does not possess mass or gravity, it neither offers resistance, nor does work. Next there is the element of *tamas*, mass, inertia, matter-stuff, which offers resistance to motion, as well as to conscious reflection.
