At Tara in this fateful hour

Christo-Celtic Prayer Against the Powers of Darkness
attributed to St. Patrick

At Tara in this fateful hour
I place all Heaven with its power
and the sun with its brightness
and the snow with its whiteness
and the fire with all the strength it hath
and the lightning with its rapid wrath
and the winds with their swiftness along their path
and the sea with its deepness
and the rocks with their steepness
and the earth with its starkness--
all these I place
by God's almighty help and grace
between myself and the powers of darkness.
Amen.

~ quoted by Madeleine L'Engle, A Swiftly Tilting Planet, p. 288-9
