The dust of many crumbled cities settles over us like a forgetful doze, but we are older than those cities. We began as a mineral. We emerged into plant life and into the animal state, and then into being human, and always we have forgotten our former states, except in early spring when we slightly recall being green again. That's how a young person turns toward a teacher. That's how a baby leans toward the breast, without knowing the secret of its desire, yet turning instinctively. Humankind is being led along an evolving course, through this migration of intelligences, and though we seem to be sleeping, there is an inner wakefulness that directs the dream, and that will eventually startle us back to the truth of who we are.
