When we see wonderful things happening in the cosmic nature, we should know that behind these wonderful manifestations, there is a controller. Nothing can be manifested without being controlled. It is childish to, not to consider about the controller. Just like a very nice motor car with very good speed and very good engineering arrangement is running on the street. A child may think that "How this motor car is running without the help of any horse or any pulling agent?" But a sane man or an elderly person, he knows that in spite of all engineering arrangements in the motor car, without the driver it cannot move.
