You'll find, it is analyzed like this, that all this material nature—I mean to say, earth, water, fire, air, ether, mind, intelligence and ego—these eight, these eight kinds of material nature, they are, and they have been described as aparā. Aparā means inferior.
And beyond this eight nature, there is another, ninth nature. And which is that? Now, jīva-bhūtāṁ mahā-bāho: these living entities. That is the living force. The living force, that is superior nature, and this matter is inferior nature. And the whole world is moving due to the superior nature, not the material, inferior nature.
Just like this tape recorder . . . there was some difficulty in running on. So as soon as some superior nature, some living entity comes and touches it, it goes on. Although the machine is all right, so unless there is touch of the superior nature, it cannot work. You have manufactured many wonderful machines. You have manufactured the Sputnik, flying in the outer space, but do you know that in spite of all wonderful mechanical arrangement of Sputnik or any machine, can it go on without any touch of a man? No. Unless the man in the laboratory touches the switch of electronic machine, oh, the Sputnik cannot fly in the space. That is not possible.
Therefore, however wonderful may be the sputnik machine, unless there is touch of the living force, it cannot go on. That is the distinction between superior nature and the inferior nature. You can understand.
