Both the material and spiritual worlds belong to Kṛṣṇa. We are not proprietors of anything. It is all the property of the Supreme Lord, just as everything in the state belongs to the government, either in the prison house or outside the prison house. Conditioned life is just like life in a prison house in this material world. A prisoner cannot freely change from one cell to another. In free life one can go from one home to another home, but in prison life one cannot do that but must stay in his cell. All these planets are like cells. We are trying to go to the moon, but it is not practical by mechanical means. Whether we are American, Indian, Chinese or Russian, we have been given this planet to live on. We cannot leave—although there are millions and billions of planets and although we have machines by which we can—because we are conditioned by the laws of nature, God's laws. A man who is put into a certain cell cannot change at will without superior authority. Kṛṣṇa says in the Bhagavad-gītā that one should not try to change from one cell to another. That will not make anyone happy. If a prisoner thinks, "I am in this cell—let me request the warden to change my cell, and I will be happy," that is a mistaken idea. One cannot be happy so long as he is within the prison walls. We are trying to be happy by changing cells—from capitalism to communism. The aim should be to become free from this "ism" and that "ism." One has to change completely from this "ism" of materialism; then he can become happy. That is the program of Kṛṣṇa consciousness.
We are taking advice from the Supreme Person. He says, "My dear Arjuna, you may be elevated to the highest planetary system, which is called Brahmaloka and is desirable because life there is very long." We cannot calculate even a half-day there. It is beyond our mathematical calculations. But even in Brahmaloka there is death. Therefore Kṛṣṇa says, "Do not waste your time trying to elevate yourself or transfer yourself from this planet to that planet."
