I understand that the lyrics have been put together from pieces of "Fremen" language found in Frank Herbert's books from "Dune". From the translation of the artificial language, it can only be like a prayer song from the Alia cult described in Dune 3 (Children of Dune). It's actually a song from a constructed religion, worshipping a fake goddess, that is Alia. It's not deeper than that, but it's still a very beautiful song and poetic lyrics.
