10. And what will such a Principle essentially be?
The potentiality of the Universe: the potentiality whose non-existence would mean the non-existence of all the Universe and even of the Intellectual-Principle which is the primal Life and all Life.
This Principle on the thither side of Life is the cause of Life — for that Manifestation of Life which is the Universe of things is not the First Activity; it is itself poured forth, so to speak, like water from a spring.
Imagine a spring that has no source outside itself; it gives itself to all the rivers, yet is never exhausted by what they take, but remains always integrally as it was; the tides that proceed from it are at one within it before they run their several ways, yet all, in some sense, know beforehand down what channels they will pour their streams.
Or: think of the Life coursing throughout some mighty tree while yet it is the stationary Principle of the whole, in no sense scattered over all that extent but, as it were, vested in the root: it is the giver of the entire and manifold life of the tree, but remains unmoved itself, not manifold but the Principle of that manifold life.
