The Supreme Personality of Godhead and material nature work together to maintain this great universe, and not only this universe but also the millions of other universes beyond this one.
The question of how the planets and stars are floating is also answered in this verse. It is not because of the laws of gravity. Rather, the planets and stars are enabled to float by manipulations of the air. It is due to such manipulations that big, heavy clouds float and big eagles fly in the sky. Modern airplanes like the 747 jet aircraft work in a similar way: by controlling the air, they float high in the sky, resisting the tendency to fall to earth. Such adjustments of the air are all made possible by the cooperation of the principles of purusa (male) and prakrti (female). By the cooperation of material nature, which is considered to be prakrti, and the Supreme Personality of Godhead, who is considered the purusa, all the affairs of the universe are going on nicely in their proper order. Regarding the great eagles mentioned in this verse, it is understood that there are eagles so big that they can prey on big elephants. They fly so high that they can travel from one planet to another. They start flying in one planet and land in another, and while in flight they lay eggs that hatch into other birds while falling through the air. In Sanskrit such eagles are called syena. Under the present circumstances, of course, we cannot see such huge birds, but at least we know of eagles that can capture monkeys and then throw them down to kill and eat them. Similarly, it is understood that there are gigantic birds that can carry off elephants, kill them and eat them. The two examples of the eagle and the cloud are sufficient to prove that flying and floating can be made possible through adjustments of the air. The planets, in a similar way, are floating because material nature adjusts the air according to the orders of the Supreme Lord. It could be said that these adjustments constitute the law of gravity, but in any case, one must accept that these laws are made by the Supreme Personality of Godhead. The so-called scientists have no control over them. The scientists can falsely, improperly declare that there is no God, but this is not a fact.
