The light of the soul throws sparks, can set up flares, builds fires, causes proper matters to catch fire. To display the lantern of the soul in shadowy times like these, to be fierce and to show mercy toward others, both, are acts of immense bravery and greatest necessity. Struggling souls catch lights from other souls who are fully lit and willing to show it.
Just as each soul spark of every living cell in our bodies makes up that which we call our soul, so too do all living souls in the world cumulatively make up part of a universal soul. Indeed, mysticism teaches us that the soul giving us vitality is connected to, and draws sustenance from, a universal soul.
