I have an example of metaphor from the East about the purity. In the West,diamant is the symbol of purity but in Orient, it's the lotus.But I'm not sure.could you tell me it's really a metsphor this kind of folksong:
Nothing is more besutiful thsn the lotus in t he pond
Green leaves, white flowers snd an added yellow pollen
Yellow pollen,white flowers, green leaves
Is next to the mud but doesn't smell this odour.
