You multiply three into three, it becomes nine. And if you multiply nine into nine, you become . . . you see eighty-one. So therefore all these varieties of life, they are being controlled, because . . . not controlled. He accepts to be controlled. Prakṛti does not want . . . nature does not want to control you.
