I wrote that. All is Vanity means all is competition for things of value. Representation of all raises an anger that forbids display of small things here, so that a robber can claim greatness heaping wealth. We never actually represent all, always a majority. So all is Vanity works on Two levels like all good Statements or Jokes.
Beware! Let your Garment always be White means the Chalk of building & restoring. Garments of White thread mean all things are possible concerning conduct.
