纯度

Maturity is wanting nothing but what we see with the purity of our heart. - Hugh Prather
A lovely nook of forest scenery, or a grand rock, like a beautiful woman, depends for much of its attractiveness upon the attendance sense of freedom from whatever is low; upon a sense of purity and of romance.- P. T. Barnum
There are few sights more pleasant to the eye than a wide cotton field when it is in bloom. It presents an appearance of purity, like an immaculate expanse of light, new-fallen snow. - Solomon Northup
