The Light and Darkness have no bodies.

And the Darkness when it is swallowed here by the Light has not even a body ; for nothing is separated from itself (i.e., the Darkness), seeing that it vanishes altogether. But a house full of darkness shows that if a man opens the doors [P. 80, 11.] and windows in the daytime, whither can that darkness, which is in it, go up [to hide]? There is no room for it to go outside, for the Light which is from outside absorbs it. If we say that it stays within, it does not remain there. For the rays of the Sun entering pursue it. And if it does not exist within, and goes out, it is clear that it has all come to an end ; and with it has come to an end all that Teaching which says that it (i.e., Darkness) has a kind of body in reality. For in this manner it (i.e., the Teaching) says that it has a body, in that "it verily ate those brilliant Shining Ones (ZIWANE) who were cast into its mouth." So Darkness and Light have become composite bodies -- a thing which nature does not teach. For a man never eats Light nor ever swallows Darkness.
