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.
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 heaven's joys, O bright heaven's Sun!
Heart of my own heart, whatever befall,
Still be my Vision, O Ruler of all.
