Donald Marquis (D.R.P. Marquis) ("Don Marquis") once said...
A fierce unrest seethes at the core
Of all existing things:
It was the eager wish to soar
That gave the gods their wings.
. . . .
There throbs through all the worlds that are
This heart-beat not and strong,
And shaken systems, star by star,
Awake and glow in song.
