When we want to lift something heavy with a hoist or a pulley, we have to anchor our leverage firmly on the ground.
When we build a wall for a house, we make sure of solid foundations.
Similarly, the Divine soul of man had to be fastened to something firm and steady like the earth.
From this base the plantlike growth force in man could take root and the rest of his animal powers could issue.
For man is also the lever and the hoist of all of creation, the factor that can raise the essentially inert parts of the world.
Only with man's interference can the rest of creation rise out of itself.
