Hi
lucidservant - and welcome to comparative-religion.com!
I think somehow we're harking very much back to Plato here, with his shadows on the cave wall - which, perhaps, is a particular focus for Eastern Thought (where's Vajradhara?

).
And, of course, there's the familiar allegory (or should that be metaphor?

) that "All the world's a stage".
But made of light - perhaps not. After all, we are already composed of condensed energy.
