At Tara, in this fateful hour,
I call all Heaven with it's power,
the sun with it's brightness,
the snow with it's whiteness,
the fire with all strength it hath,
the lightening with it's rapid wrath,
the winds with their swiftness along their path,
the sea with it's deepness,
the rocks with their steepness,
the Earth with it's starkness.
All these I place,
by God's Almighty help and grace,
between myself and powers of darkness.

Madeleine L'Engle
