"This material nature is working under My direction, O son of Kuntī, and producing all moving and nonmoving beings." (Bg. 9.10) Nature works under the supervision of God, Kṛṣṇa, so how can nature make mistakes? But  we  commit mistakes, we are illusioned, our senses are imperfect, and we cheat. That is the difference between God and man. God does not have imperfect senses; His senses are perfect.
Satisfied Animals
Dr. Wolf-Rottkay.  Because our senses are defective, the technological enlargements of our senses must also be defective, of course.
Dr. Singh.  The microscopes with which we detect things must also be defective.
Śrīla Prabhupāda.  Material existence  means  defective existence. If you construct something with defective knowledge and imperfect senses, whatever you construct must be defective.
Dr. Singh.  Even if scientists devised a perfect microscope, they would still have to look through it with defective eyes.
Śrīla Prabhupāda.  Yes. That is right. Therefore we conclude that whatever the scientists may say is defective.
Dr. Singh.  But they seem quite satisfied..
Śrīla Prabhupāda.  The ass is also satisfied. The ass is satisfied to carry the load of the washerman. Everyone is satisfied, even the worm in the stool. That is nature's law.
Dr. Wolf-Rottkay.  It is said that even the pauper is proud of his penny.
Śrīla Prabhupāda.  Yes. In some parts of India one may sometimes see a dog starving to death. But as soon as it gets a female dog, it is satisfied with having sex. Is that satisfaction? The dog is starving, but still it is satisfied with sex.
