How does Tony Kushner use imagery in Millennium Approaches?

Imagery:

Your clay is the clay of some Litvak shtetl, your air the air of the steppes—because she carried the old world on her back across the ocean, in a boat, and she put it down on Grand Concourse Avenue, or in Flatbush, and she worked that earth into your bones, and you pass it to your children, this ancient, ancient culture and home."

"A marvelous work and a wonder we undertake, an edifice awry we sink plumb and straighten, a great Lie we abolish, a great error correct, with the rule, sword and broom of Truth!"
