That's the text to-day for reading

That's the text to-day for reading
Nature and its being by?
There is effort all the morning
Thro' the windy sea and sky.

All, intent in earnest grapple
That the All may let it be:
Force, in unity, at variance
With its own diversity.

Force, prevailing into action,
Force, persistent to restrain,
In a twofold, one-souled wrestle
Forging Being's freedom-chain.

Frolic! say you— when the billow
Tosses back a mane of spray?
No; but haste of earnest effort;
Nature works in guise of play.

Till the balance shall be even
Swings the to and fro of strife;
Till an awful equilibrium
Stills it, beats the Heart of Life.

What's the text to-day for reading
Nature and its being by?
Effort, effort all the morning,
Thro' the sea and windy sky.
