Motion Is the Life of All Things

As darknesse a privation is of Light;
That's when the Optick Nerve is stopt from Light:
So Death is even a cessation in
Those Formes, and Bodies, wherein Motions spin.
As Light can only shine but in the Eye,
So Life doth only in a Motion lye.
Thus Life is out, when Motion leaves to bee,
Like to an Eye, that's shut, no Light can see.
