God's machine is so perfect that it is automatically taking place. Parasya shaktir vividhaiva shruyate [Chaitanya-charitamrita Madhya 13.65, purport]. Shakti. God's energy, Krishna's energy, is so perfect that it is automatically being done.

We have got some experience nowadays. The pilot is sitting in front of the airplane, and there are very fine electronic machine, and he's pushing one button. Immediately the wings is working, and it is going down, it is, it is very, mean, a delicate position in the air. A little mistake in the pushing of the button, the whole plane may be crashed. So nowadays scientists, they have invented so many fine machineries that it is working very nicely. We came from London to Bombay in eight hours. So this is very nice.

But at the same time, we should appreciate that how much nice machinery is there which is conducting the whole cosmic activities. So that is stated in the Vedas, that parasya shaktir vividhaiva shruyate, svabhaviki jñana-bala-kriya cha. Krishna's knowledge is so perfect. Krishna says, mayadhyakshena prakritih suyate sa-characharam [Bhagavad-gita 9.10]. This nature's work is going on not whimsically, but under the guidance of pushing the button of Krishna, by Krishna. It is not going on independently. Any scientist can understand that no machine, however nicely made, finely made, without pushing the button, it cannot work. So the huge machinery of the cosmic manifestation, which is working so nicely and perfect, perfectly, there must be some brain. All big, big scientists, even Professor Einstein, he also admitted. So there is brain. That brain is Krishna.
