"/At every moment he beholdeth a wondrous world, a new creation, and 
goeth from astonishment to astonishment, and is lost in awe at the works 
of the Lord of Oneness./"     Baha'u'llah, The Seven Valleys
"./.. humans are interesting. With all the wonders there are in the 
Universe, they invented boredom./"     Terry Pratchet, Hogfather
"/The most beautiful thing we can experience is the mysterious. It is 
the source of all true art and all science. He to whom this emotion is a 
stranger, who can no longer pause to wonder and stand rapt in awe, is as 
good as dead: his eyes are closed./"     Albert Einstein
/"Stuff your eyes with wonder ... live as if you'd drop dead in ten 
seconds. See the world. It's more fantastic than any dream made or paid 
for in factories./"     Ray Bradbury
