“I see my way as birds their trackless way.
I shall arrive! what time, what circuit first,
I ask not; but unless God send his hail
Or blinding fire-balls, sleet or stifling snow,
In some time, his good time, I shall arrive:
He guides me and the bird. In his good time!”

“Paracelsus” -Part I.
by Robert Browning [1812-1889]
