13. Concerning the Lost Temple and How it is to be Restored III (In connection with the Legend of the True Cross, or Golden Legend)
The lowest principle in man, [the physical body,] must indeed still pass through these three kingdoms, just as it is at present passing through the Mineral Kingdom. Just as today man lives in the Mineral Kingdom with his physical nature, so in the future he will live in the Plant Kingdom, and then rise to still higher Kingdoms. Today with our physical nature we are in a transitional stage between the Mineral and Plant Kingdoms, with our etheric nature in transition from the Plant Kingdom to the Animal Kingdom, and with our astral nature in transition from the Animal Kingdom to the Human Kingdom. And finally, we extend beyond the three Kingdoms into the Divine Kingdom, with that part which we have in the Sphere of Wisdom, where we extend in our own nature beyond the astral.
