By "wayward light" I mean "will-o-the
whisp" (onibi).
Kaya went over this in his interview, but the mirror
he speaks of is called [Jouhari] and belongs to Emna,
the Lord of the underworld. When the dead come before
him for their judgement he uses it to view the sins they
had comitted during life and determine their fates as
such. Basically it reflect truth. I think it was in Yuuyuu
Hakusho too.
Well, that aside, mirrors play an interesting symbolic
role in Japan. It was once believed, and may indeed still
be believed by some, that mirrors provided a way for the
dead to communicate with the living. In fact, it has been
speculated by anthropologists that the big mirror at the
end of the Yasukuni museum is placed there to remind people
of those who died during the War. I guess there's a sense
of this in the West too since we have Bloody Mary, hm?
^^ I still won't look in the mirror when it's dark.
In this case though, I think the mirror is more of a
way of creating illusions and revealing the truth than
communicating with the dead. That part just made it goffy.
Kaya himself talked about this song being about the world
of illusions in the mirror. Mirrors are also supposed
to be able to strip away illusions and show reality though,
like the emperor's mirror. I myself like to think this
song is about guilt/escapism.
...personally, however painful, I prefer reality though....
