Question: Will there always be an animal kingdom, a plant kingdom and all the other lower kingdoms?

Sri Chinmoy: This kind of thing may change if the process of evolution changes. At that time there would be no place for stones or plants in the evolutionary process. There is a possibility that one day the Supreme will change the process of evolution, but right now that is not His plan.
