Emanation, the Doctrine of, a doctrine of Eastern origin, which derives everything that exists from the divine nature by necessary process of emanation, as light from the sun, and ascribes all evil and the degrees of it to a greater and greater distance from the pure ether of this parent source, or to the extent in consequence to which the being gets immersed in and clogged with matter.
Definition taken from The Nuttall Encyclopædia, edited by the Reverend James Wood (1907)
