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!
