 Think for a second about what it feels like to be a person. Every thought and mindscape, every color, dream, and imagining you've ever had. Are you not yourself an entire world? There are in fact many worlds inside you, which will grow in the dirt and sun, depend on which you water, how the wind blows, where snow falls, where wildfires rage. It's not entirely up to us how new worlds unfold, but we're not entirely powerless either.
