Be thou my vision, oh lord of my heart
Nought be all else to me, save that thy art
Thou my best thought in the day and the night
Waking or sleeping, thou presence my light

Be thou my wisdom, be thou my true word
I ever with thee and thou with me lord
Thou my great father and I thy true son
Thou in me dwelling and I with thee one
[ Lyrics from: http://www.lyricsfreak.com/v/van+morrison/be+thou+my+vision_20143050.html ]
Be thou my breastplate, my sword for the fight
Be thou my armour and be thou my might
Thou my soul shelter, and thy my high tower
Raise thou me heavenwards, oh power of my power

Riches I need not, nor mans empty praise
Thou mine inheritance through all of my days
Thou and thou only though first in my heart
High king of heaven my treasure thou art

Oh high king of heaven, when battle is done
Grant heavens joy to me, bright heaven sun
Christ of my own heart, whatever befall
Still be my vision, though ruler of all

Da, da, da, da, da, etc.
