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."
The people I have seen in America are very restless. They go from one apartment to another apartment or from one country to another country. That restlessness is there because we are searching after our real home. To go from this place to that place will not give eternal life. Eternal life is with Kṛṣṇa. Therefore Kṛṣṇa says, "Everything belongs to Me, and I have the superexcellent abode, which is called Goloka Vṛndāvana." If one wants to go there, he must simply become Kṛṣṇa conscious and try to understand how Kṛṣṇa appears and disappears, what His constitutional position is, what our constitutional position is, what our relationship with Him is, and how to live. Simply try to understand these ideas scientifically. Everything in Kṛṣṇa consciousness is scientific. It is not bogus, whimsical, sentimental, fanatical or imaginary. It is truth, fact, reality. One must understand Kṛṣṇa in truth.
We have to give up this body, willingly or unwillingly. The day will come when we will have to submit to the laws of nature and give up this body. Even President Kennedy in his procession had to submit to nature's law and change his body for another body. He could not say, "Oh, I am the President; I am Mr. Kennedy. I cannot do that." He was forced to do it. That is the way nature works.
The purpose of our developed human consciousness is to understand how nature works. Aside from human consciousness, there is consciousness in dogs, cats, worms, trees, birds, beasts and all other species. But we are not meant to live in that consciousness. The Śrīmad-Bhāgavatam says that after many, many births we have attained the human form of body. Now we should not misuse it. Please utilize this human life to develop Kṛṣṇa consciousness and be happy.
