XI. Who are the Rosicrucians?

All this must be thought of in conjunction with what was said about the Holy Grail: that the purity and chastity of the plant nature would pan over into human nature. When a person's lower nature has reached the highest level of spirituality, it will in that respect be once more at the level of the plant as it is today. The process that takes place in the plant, a person will one day be able to carry out in his own being. He will more and more transform the substance of his present body into the ideal of a plant body, which will be the bearer of a much higher and more spiritual consciousness. Thus, the Rosicrucian pupil learns the alchemy that eventually will enable a person to transform the fluids and substances of the human body into carbon. Thus, what the plant does today—it builds its body from carbon—human beings will one day accomplish. He will build a structure from carbon that will be a person's future body. A great mystery lies hidden in the rhythm of the breath.
