Each of the said kingdoms has sprung from the preceding one, and each preceding kingdom has developed into the succeeding kingdom. In the mineral kingdom one sees by a careful study how the rock has developed into metal, and from metal into softer earthy substance, until it develops into the plant. And one sees how the development of the plant creates germs and worms, which we call lives, and how from their germ and worm state of being they develop into insects, birds, and beasts. This all shows that nature is working continually to rise to a greater consciousness of life, and finds its satisfaction at last when it has accomplished its journey by rising to its natural and normal state of being, which it accomplishes in man.
