The human brain is finite – no more than a sponge of tissue inside a cage of bone – but the mind within the brain is infinite. Its storage capacity is colossal, its imaginative reach beyond our ability to comprehend. I think when a man or woman dies, a whole world falls to ruin – the world that person knew and believed in. Think of that, kiddo – billions of people on earth, and each one of those billions with a world inside. The earth their minds have conceived.
