How but in custom and in ceremony are innocence and beauty born? - William Butler Yeats

I sat, a solitary man,
In a crowded London shop,
An open book and empty cup
On the marble table-top.
While on the shop and street I gazed
My body of a sudden blazed;
And twenty minutes more or less
It seemed, so great my happiness,
That I was blessed and could bless.

For he would be thinking of love
Till the stars had run away
And the shadows eaten the moon.

WINE comes in at the mouth
And love comes in at the eye;
That's all we shall know for truth
Before we grow old and die.
I lift the glass to my mouth,
I look at you, and sigh.
