You know, it's good to have reminders from faery-lore and other places that what we see is not necessarily all there is. We need the reminder to the arrogance of science that the empirical is not the end of reality--nor is it even the REALLY important part.
So:
from Songs from the Wood "Jack-in-the-Green"
Jethro TullThe rowan, the oak and the holly tree
Are the charges left for you to groom.
Each blade of grass whispers Jack-In-The-Green.
Oh Jack, please help me through my winter's night.
And we are the berries on the holly tree.
Oh, the mistlethrush is coming, Jack,
Put out the light.
