Srila Prabhupada….” Can you give us any solitary example that any wonderful thing has happened without a brain behind it? You cannot say. You cannot give even a single example within your experience. How we can say that this material nature, such wonderful things, manifestation… Thousands and millions of planets, they are floating in weightlessness in the air. There is no brain behind it? You throw one mechanical sputnik, and there are thousands of scientists working in the laboratory, electronics. They are pushing on the button, and everything is recorded. A plaything only. That sputnik is a plaything.

If for such a plaything so many scientists, so many brain, are working, do you think such wonderful things are happening without any brain? This is called foolishness. Foolish people will say that they are taking (place) automatically. No. They are not taking place automatically.”
