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.
Somewhere downstairs a door slammed, and my father entered the house laughing. Instantly, the whole universe joined in. Great roars of hilarity sounded from sun to sun. Field mice uttered, and so did angels and rainbows. Laughter leavened every atom and every star until I saw a universe inspirited and spiraled by joy, not unlike the one I read of years later when Dante describes his great vision in paradise.
"D'el riso d'el universo." (The joy that spins the universe). This was a knowledge of the way everything worked. It worked through love and joy and the utter interpenetration and union of everything with the All That Is.
