'REFUSE, refrain: for this is not the love
The Annunciation Angel warned you of;
This is the little candle, not the sun;
It burns, but will not warm, unhappy one!'

'But ah! suppose the sun should never shine,
Then what an anguish of regret were mine
To know that even from this I turned away!
Candles may serve, if there should be no day.'

'Nay, better to go cold your whole life long
Than do the sun, than do your soul such wrong:
And if the sun shine not, be life's the blame
And yours the pride, who scorned the meaner flame.'

Edith Nesbit
