I know not how Thou singest

I know not how Thou singest ...
I ever listen in silent amazement.
The light of Thy music illumines the world.
The life breath of Thy music runs from sky to sky.
The holy stream of Thy music breaks through all stony obstacles
and rushes on.
My heart longs to join in Thy song, but vainly struggles for a voice.
I would speak but speech breaks not into song,
and I cry out baffled.
Ah, Thou has made my heart captive in the endless meshes of my music ...
