I kiss you and kiss you, With arms around my own, Ah, how shall I miss you, When, dear, you have grown. - William Butler Yeats

Of all the many changing things
In dreary dancing past us whirled,
To the cracked tune that Chronos sings,
Words alone are certain good.

Some may have blamed you that you took away
The verses that could move them on the day
When, the ears being deafened, the sight of the eyes blind
With lightning, you went from me, and I could find
Nothing to make a song about but kings,
Helmets, and swords, and half-forgotten things
That were like memories of you--but now
We'll out, for the world lives as long ago;
And while we're in our laughing, weeping fit,
Hurl helmets, crowns, and swords into the pit.
But, dear, cling close to me; since you were gone,
My barren thoughts have chilled me to the bone.

Every conquering temptation represents a new fund of moral energy. Every trial endured and weathered in the right spirit makes a soul nobler and stronger than it was before.
