The nature is instrument. Just like any machine. Take typewriter machine. The typewriter machine or any machine, working very nicely, but the machine is not working nicely; the man, the person who is typing, he is doing nicely. There may be wonderful machine, computer, but there must be one actor, one manipulator. So the . . . this nature is an instrument only. The actually worker is Kṛṣṇa. That is described in the Bhagavad-gītā: mayādhyakṣeṇa prakṛtiḥ sūyate sa-carācaram (BG 9.10). But these rascals, they are praising the machine. They have no information that who is the person, what is the brain behind this machine. That is ignorance. That is the difference between the so-called scientists and devotee. A devotee knows that all these wonderful things which are happening, behind this thing there is Kṛṣṇa. And Kṛṣṇa says—we believe that.
And that's a fact. If you paint a very nice flower, how much labor you require. Still, it cannot be so beautiful as the natural flower. So don't think the natural flower has come accidentally. No. It was done by the machine manipulated by Kṛṣṇa. That is Kṛṣṇa understanding. It is confirmed in the śāstra, parasya śaktir vividhaiva śrūyate (Śvetāśvatara Upaniṣad 6.8). Para, the Supreme, His energies are multi-energies. They are acting, the same way the machine is working. You can see potency or the power of a person. Just like you see airplane: the pilot is sitting there, pushing one button; immediately the turning, such a huge machine is turning, simply by putting button. So this is an arrangement of energy. Similarly, the whole material world is working by putting the button, pushing the button. Don't think it is going on automatically or accidentally. These are all rascaldom. There is hand in everywhere.
