The Heart's Astronomy by Julia Ward Howe (1890-1910)

This evening, as the twilight fell,
My younger children watched for me;
Like cherubs in the window framed,
I saw the smiling group of three.

While round and round the house I trudged,
Intent to walk a weary mile,
Oft as I passed within their range,
The little things would beck and smile.

They watched me, as Astronomers,
Whose business lies in heaven afar,
Await, beside the slanting glass,
The re-appearance of a star.

Not so, not so, my pretty ones,
Seek stars in yonder cloudless sky;
But mark no steadfast path for me,
A comet dire and strange am I.

Now to the inmost spheres of light
Lifted, my wondering soul dilates;
Now, dropped in endless depth of night,
My hope God's slow recall awaits.

Among the shining I have shone,
Among the blessings have been blest;
Then wearying years have held me bound
Where darkness deadness gives, not rest.

Between extremes distraught and rent,
I question not the way I go;
Who made me, gave it to me, I deem,
Thus to aspire, to languish so.

But comets, too, have holy laws,
Their fiery sinews to restrain,
And from their outmost wanderings
Are drawn to heaven's dear heart again.

And ye, beloved ones, when ye know
What wild, erratic natures are,
Pray that the laws of heavenly force
Would help and guide the Mother star.

Today I discovered this brilliant poet who I'm sure you'd like.
