The Land of the Dead is many lands. Lands in every direction. Lands as far as the eye can see, the ear can hear, and the feet may travel. Lands above and below. Lands to the north, lands to the south. Lands to the east and the west and all points in between.
Each death is a land unto itself, and all of these lands lie together—touching, close, and in intimate communion and conversation. The messages that travel between them require no time. What one knows, they all know. What one feels, they all feel. What one does, they all do. The Dead are of one body, one spirit, one mind. Nothing is hidden from them, and nothing is impossible for them. No one is beyond their reach. No one can fathom them or understand them. No one can harm them. They are beyond all injury.
But everyone can speak to them, feel their presence, and receive their guidance. This is really all you need to know.
People speculate about religion before religion, what their earliest ancestors believed. I tell you it is this: the Land of the Dead is many lands, but those lands all lie together. They belong to one body, one soul, one spirit, and one mind.
