Kai - Meaningless or Meaningless?

Many of these gobbledygook phrases that appear in the magical diary can be shown to be garbled versions of phrases from other languages. Were these things always meaningless? Probably not. There's a sense in which they become meaningful again and they often become sort of associated with the names of demons. It seems to me very simplistic here and very partial but we do sometimes this wonderful transition from meaninglessness to meaningfulness again with the vocation of kai.
