In harmony with the Tao,
the sky is clear and spacious,
the earth is solid and full,
all creatures flourish together,
content with the way they are,
endlessly repeating themselves,
endlessly renewed.

when man interferes with the Tao
the sky becomes filthy,
the earth becomes depleted,
the equilibrium crumbles,
creatures become extinct.
