The Weakest Thing by Elizabeth Barrett Browning

Which is the weakest thing of all
Mine heart can ponder?
The sun, a little cloud can pall
With darkness yonder?
The cloud, a little wind can move
Where’er it listeth?
The wind, a little leaf above,
Though sere, resisteth?

What time that yellow leaf was green,
My days were gladder;
But now, whatever Spring may mean,
I must grow sadder.
Ah me! a leaf with sighs can wring
My lips asunder
Then is mine heart the weakest thing
Itself can ponder.

Yet, Heart, when sun and cloud are pined
And drop together,
And at a blast, which is not wind,
The forests wither,
Thou, from the darkening deathly curse
To glory breakest,
The Strongest of the universe
Guarding the weakest!
