O YE SEEMING FAIR YET INWARDLY FOUL! Ye are like clear but
bitter water, which to outward seeming is crystal pure but of which, when
tested by the divine Assayer, not a drop is accepted. Yea, the sun beam falls
alike upon the dust and the mirror, yet differ they in reflection even as doth
the star from the earth: nay, immeasurable is the difference!
- Baha’u’llah (‘The Hidden Words of Baha’u’llah’)
