I figured I would be really geeky with this and try to find the meaning of the word in Risshizentsukuyomi. (see here: http://conlang.wikia.com/wiki/Hymmnos#Grammar_.28Risshizentsukuyomi.29 )
P - -
A - Power
N - Nothing, Empty, emptiness
D - Darkness, Demon
O - Evil, wicked, dark
R - Life
A - Power
hymme [object]: Oh Power through your empty darkness and to my wicked life bestow power
EDIT: I could be translating this very wrong, and if someone knows enough about it to correct me, I invite you to do so.
