Why did Hashem create things to work like they do?
Is Hashem describing a spiritual world, or the spiritual world, with his creation on earth? He could have created it in so many ways; why this way?
"Man in his own image". . . what about everything else?
Is everything in the universe a metaphor for a spiritual world? (If not then what? Because it looks nice?)
The Torah, sages, talmud must comment on this question in many ways.
