What are the Pain's theme song lyrics? When Pain appears in Naruto Shippuden, there is always a good background music named Girei that is played. 

I wanted to know the lyrics, so I looked it up on the net and found a few results that state that the lyrics are in English. Here are the results I found:

Version 1:


  As we forgive for love
  but we can not pull through
  if we can not forgive
  we all tribute to love


Version 2:


  As we forgive for love
  but we can not pull through
  if we can not forgive
  for our tribute true love


And Version 3 (the phonetic one):


  meh-shea-fu-ni coo-ma
  mah-ni-kay-nah-bow-coo
  ee-ee-kay-nah for-gee
  kor-ah-tay-boo troo- la or bah or ma


But I'm still convinced that the song is definitely Japanese. 

Can anyone who is/knows Japanese confirm this?
Long shot, guys, but don't you think that if it's a chant it can be in Chinese?
For example like this:

没师傅你哭吗    Méi shīfù nǐ kū ma
那你可那波苦    Nà nǐ kě nàbō kǔ


First two lines can be then read as such:

Master didn't cry for you
You can wave of that pain


Then I'd go with Japanese/English line:

いけない FORGIVE    Ikenai FORGIVE


And that one means simply:

Don't forgive


The only thing I can't possibly get is the last line... It sounds Latin-ish, but it can't be as there are no words fitting phonetically to these syllables...
It sounds between Japanese and some ancient European language...

What do you think, guys?
