*出自英国诗人布莱克的《天真的预言》（Auguries of Innocence）的开头四行—— 

"To See a World..." (Fragments from "Auguries of Innocence"by William Blake 

To see a World in a Grain of Sand 

And a Heaven in a Wild Flower, 

Hold Infinity in the palm of your hand 

And Eternity in an hour. 

一沙一世界， 

一花一天堂。 

掌心握无限， 

刹那是永恒。
