I very much like the philosophical criticism behind this poem (we humans take our darkness everywhere, however light it is!) but I'm still thinking over the image choice - he looks a bit unconcerned for a stumbler!

"Single moon" is also interesting (as they don't come in pairs). I wonder what the original character is. Might it be "solitary" (i.e. unaccompanied) rather than numerically single? Just a thought.

Thanks for putting a bit of Zen our way!
