In The Willow Shade Christina Rossetti

I sat beneath a willow tree,
        Where water falls and calls;
While fancies upon fancies solaced me,
        Some true, and some were false.

Who set their heart upon a hope
        That never comes to pass,
Droop in the end like fading heliotrope,
        The sun's wan looking-glass.

Who set their will upon a whim
        Clung to through good and ill,
Are wrecked alike whether they sink or swim,
        Or hit or miss their will.

All things are vain that wax and wane,
        For which we waste our breath;
Love only doth not wane and is not vain,
        Love only outlives death.

A singing lark rose toward the sky,
        Circling he sang amain;
He sang, a speck scarce visible sky-high,
        And then he sank again.

A second like a sunlit spark
        Flashed singing up his track;
But never overtook that foremost lark,
        And songless fluttered back.
