XI. Who are the Rosicrucians?

You will now understand the notice about the philosopher's stone alluded to earlier. But what is it that human beings will learn in regard to building up the human body in the future? They will learn to create ordinary coal—which is also what diamonds consist of—and from it build their body. Human beings will then possess a higher and more comprehensive consciousness. They will be able to take the carbon out of themselves and use it in their own being. They will form their own substance, that is, plant substance made of carbon. That is the alchemy that builds the philosopher's stone. The human body itself is the retort, transformed in the way indicated.
