They sang a capella: one voice began to mount like a skylark and detach itself from the rest, from those mingled voices which together sounded well, but from whose conjunction with this single one soared in an intensity of beauty — a voice so clear and just, yet vibrant with such warm sweetness, I have remembered it always. The fact that this great, this glorious and rare voice was singing behind bars, that the face and identity of this singing nun would forever be unknown to us, shadowed the music. Mainly, we were awed to think this treasure was so hidden.
Only the Spirit of the Holy One can impart to the human spirit the knowledge of the holy. Yet as electric power flows only through a conductor, so the Spirit flows through Truth and must find some measure of Truth in the mind before It can illuminate the heart. Faith wakes at the voice of truth but responds to no other sound... Still, there must be humble penitence in the heart before Truth can produce faith.
