What exactly is Loreena Incanting?

Has anyone else wondered? That song ("Incantation") is one of her most beautiful, eerie, and, baffling to me. Because it seems she's not only singing a series of "las, lees, or loos.. It, to me sounds like she's speaking some type of language, while it's probably just a "made up" language it's still very interesting to contemplate what she is "incanting" perhaps it's a summoning of the atmosphere of the songs to come. But of course my metaphysical oriented head doesn't like that simple idea! haha!


I wonder the back story to this song.. It's really gorgeous and make me think of an Ancient Mediterranean culture.. like Greece or something.. the Oracle of Delphi.. the gods.. it's just mystifying. so good job Loreena!
