>The third face indeed is invisible because in temporal manifestation the present is only an imperceptible instant; but when one is elevated above the conditions of this transitory and contingent manifestation, the present, on the contrary, contains all reality. In Hindu symbolism the third face of Janus corresponds to the frontal eye of Shiva, also invisible since it is not represented by any corporeal organ and which represents the "sense of eternity"; a glance from this third eye reduces everything to ashes, that is, destroys all manifestation; but when succession is transmuted into simultaneity, the temporal into the in-temporal, all things are found again and remain in the "eternal present", so that the apparent destruction is really only a transformation.This "third face" of Janus, that is invisible, is also the same as the Hindu Third Eye of Shiva.
Creation through destruction. Order out of Chaos. Ordo Ab Chao.
