| "Prakṛti, material nature, puts us under certain condition, and we work accordingly, not independently. And the prakṛti, material nature, also working under somebody. Just like when you go on the street you see red light and green light. As soon as you see red light you stop your car. So this red light and green light is being manipulated by the police, and the police is working under government. Similarly, this whole material nature is acting like red light or green light, but behind that red light and green light there is the supreme brain. That is the Supreme Personality of Godhead. So as a layman or as child cannot understand how the red light and blue light..., green light is working... He sees simply, he thinks automatically it is being done. That is foolishness. It is not being automatically done. There is machine. There is manipulator behind this red light, this is intelligence."
