Air, fire, water and the earth evolve out of the spiritual and material staminibus in periodic cycles of time. Diverse connections of water, air, and light precede the emergence of the seed of the simplest plant, for instance moss. Many plants had to come into being, then die away before an animal emerged. Insects, birds, water animals, and night animals preceded the present animal forms; until finally the crown of earthly organization appeared-the human being, microcosm. He is the son of all the elements and beings, Nature's most carefully chosen conception and the blossom of creation. He must be the youngest child of Nature; many evolutions and revolutions must have preceded his formation.
