Beautiful! Its amazing how each person or group can make this song their own. You can compare one to another, but in some senses each great rendition stands alone. I love this one. Sinead O'Connor's is good and so is Eva Casidy.
As the old saying goes, its ok to do wrong if you know what right is. I think that she is trying to match the flute's timber. But who knows, I still love it.

Do you mean the scientific aether, the Hindu form, the Sanskrit form, or the classical Greek "upper sky" form?
