To-day's Burden

"Arise, depart, for this is not your rest."
Oh, burden of all burdens,--still to arise
And still depart, nor rest in any wise!
Rolling, still rolling thus to east from west,
Earth journeys on her immemorial quest,
Whom a moon chases in no different guise.
Thus stars pursue their courses, and thus flies
The sun, and thus all creatures manifest
Unrest, the common heritage, the ban
Flung broadcast on all humankind,--on all
Who live; for living, all are bound to die.
That which is old, we know that it is man.
These have no rest who sit and dream and sigh,
Nor have those rest who wrestle and who fall.
