I used to think that once you really knew a thing, its truth would shine on forever. Now it's pretty obvious to me that more often than not the batteries fade, and sometimes what you knew even goes out with a bang when you try and call on it, just like a light bulb cracking off when you throw the switch.
Does something which exists on the edge have no true relevance to the stable center, or does it, by being on the edge, become a part of the edge and thus a part of the boundary, the definition which gives the whole its shape?
