I don't think that Ghidorah's Theme should be a page yet. The lyrics on there aren't official & McCreary stated his quartet chanted "Hannya Shingyo, The Heart Sutra, a text which is universal to all the sects." from (https://www.bearmccreary.com/#blog/blog/films/godzilla-king-of-the-monsters/)

I'm unsure where the lyrics came from (aside from here) or what language they're in, but they do seem to be accurate... at least for the quieter parts where I can actually make the words out. But best to sandbox it for now, yeah.
I suggest we email to Bear McCreary or to the Director to see if they know.
