New York, December 16, 1966
There is a system. In the process of this material world there is a system. Just like for maintenance of your state, United States, there is system of government, and there is an aim. Just like your government does not like that..., there should be no Communistic persons, and you write that "We trust in God." It is better to trust in God. You have got a system. Similarly, the maintenance of the whole material world, there is a system. It is not blind. Foolish creatures, they think that everything has come out of nothing, and it is being managed by nature. No. Behind nature there is God. In the Bhagavad-gītā you have learned, mayādhyakṣeṇa prakṛtiḥ sūyate sa-carācaram: [Bg. 9.10] "Under My superintendence the material nature is working." Material nature is not blind. Just like foolish person, because he cannot see President Johnson and the governmental personalities, they think, "It is going on. Nobody is there behind this government, and it is going on."
So similarly, persons who have no knowledge in the affairs of this material world, they think that "This material nature is working, and automatically, by magic, the sun is coming out, the moon is coming out, and the season is changing, and everything is going on just like magic, and we are the master of everything." Never think..., these foolish persons never think that they are not masters, they are servant, servant of the material nature.
