The moon is no door. It is a face in its own right

THEOREM XIX

"The Sun and the Moon shed their corporeal forces upon the bodies of the inferior Elements, much more so than all the other planets. It is this fact which shows, in effect, that in the pyrognomic analysis all metals lose the aqueous humour of the Moon as well as the igneous liquor of the Sun, by which all corporeal, terrestrial, and mortal things are sustained. "
