This prayer is taken from the book The Sun Dances: Prayers and Blessings from the Gaelic by Alexander Carmichael (1960).
The Peace of God, the peace of men, the peace of Columba kindly, the peace of Mary mild, the loving, the peace of Christ, King of tenderness. The Peace Christ, King of Tenderness;
Be upon each window, upon each door, upon each hole that lets in light, upon the four corners of my house, upon the four corners of my bed. Upon the four corners of my bed;
Upon each thing my eye takes in, upon each thing my mouth takes, upon my body that is of the earth and upon my soul that came from on high. Upon my body that is of the earth and upon my soul that came from on high.
Amen.
