2. The Everlasting Voices
O
Go to the guards of the heavenly fold
And bid them wander obeying your will
Flame under flame, till Time be no more;
Have you not heard that our hearts are old,
That you call in birds, in wind on the hill,
In shaken boughs, in tide on the shore?
O sweet everlasting Voices be still.
