You can see this flower. Every flower is so beautiful, nicely constructed symmetrically. You'll find two flowers, the small fiber coming out exactly in the same way. There is no question of accident. There is no question of accident. They are also being manipulated by the laws of nature. And what is the laws of nature? The laws of nature is acting under the supervision of the Supreme Personality of Godhead.
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.
