Now there's the tricky part, defining the undefineable. Rendering something sublime into something mundane.
In truth i can't furnish you with examples as such things are unique and individual. To one person a Raven's feather could be no more than trash, to another it can represent so much more.
Hence my comment regarding looking into the eyes of the Wolf. The trick is to keep one's eyes open, to search for these glimpses of the void, these epiphanies.
