Singing it now, though -- especially with the awareness of and need for (if not the active practice of) hesychia and constant remembrance of our Lord -- the verses take on a sober, almost martial tone, without triumphalism, without emotionalism ... yet still deeply moving. If you've clicked on the link already, you'll have heard most of the following verses (and, if you were watching, endured the sappy slideshow the author posted with the song). Nevertheless, here follows what I can remember of this beautiful Irish hymn of the Church:
Be Thou my vision, O Lord of my heart,
Naught be all else to me, save that Thou art.
Thou my best Thought, by day or by night,
Waking or sleeping, Thy presence my Light.
Be Thou my Wisdom and Thou my true Word,
I ever with Thee, and Thou with me, Lord.
Thou my great Father, I Thy true son,
Thou in me dwelling, and I with Thee one.
Be Thou my Battleshield, Sword for the fight,
Be Thou my Dignity, Thou my Delight,
Thou my soul's Shelter, Thou my high Tower;
Raise Thou me heavenward, O Power of my power.
Riches I heed not, nor man's empty praise,
Thou mine Inheritance, now and always.
Thou and Thou Only first in my heart;
High King of Heaven, my Treasure Thou art.
High King of Heaven, my victory won,
May I reach Heav'n's joys, O bright Heaven's Sun.
Heart of mine own heart, whatever befall,
Still be my Vision, O Ruler of all.
Amen. Sleep tight, Kati.
