Chapter ten is unusual in form. It is a series of questions, and nobody is said to answer them.
Can you hold the body and the spirit together and not let them part? Can you concentrate the breath until it is as soft as an infant's? Can you clean the dark mirror until there is no flaw in it? Can you love the people and govern the state without contrivance? Can the gates of heaven open and close, and you be the female? Can your clarity reach everywhere without your knowing anything?
The interrogative form changes what the chapter is doing. A statement would be a doctrine; a question is a test, and the reader is invited to notice that they cannot answer yes. Several of the questions describe conditions that the rest of the book treats as characteristic of the sage, so the chapter functions as a measure of distance rather than as instruction.
The content points toward a discipline of some kind. Holding body and spirit together, softening the breath and cleaning the mirror are the vocabulary of practice rather than of argument, and this chapter, with chapters six, fifty-two and fifty-five, is where the later Daoist traditions of physiological and meditative cultivation found their scriptural footing.
The atlas describes that and does not extend it. What the chapter actually prescribes, in what tradition and by what method, is not recoverable from six questions, and the practices built on it belong to living lineages with teachers.
