Waite–Smith, Trump 18
The Moon

What you can see
A crayfish emerges from water between a dog and a wolf. A path continues between two towers beneath a moon with a face.
What Waite says
Waite distinguishes imagination and reflected intellectual light from direct spiritual illumination. The animals become aspects of the natural mind confronting an unknown that this reflected light cannot fully reveal.
