Prabhupada's lecture - Śrīmad-Bhāgavatam 1.15.32 - Los Angeles, December 10, 1973
So Kṛṣṇa consciousness movement is not ordinary movement, manufacture something for recreation. No. It is very serious science. Yad gatvā na nivartante tad dhāma paramaṁ mama [Bg. 15.6]. We are searching after some permanent place, permanent settlement on the world. Nobody wants to die, but that is not possible. But if there is possibility of going somewhere where no more death, why don't you search after that? That is intelligence. That information (is) there in the Bhagavad-gītā, ābrahma-bhuvanāl lokāḥ punar āvartino 'rjuna: [Bg. 8.16] "If you go to the topmost planet which is known as Brahma-loka..."
Now, the Brahma-loka, the duration of life, you cannot calculate even their one day's time. That we were discussing this morning. That is stated in the Bhagavad-gītā.. Their twelve hours, our twelve hours and their twelve hours, different. Their twelve hours you cannot calculate: forty-three hundred thousands of years multiplied by one thousand. Now see how many years. That is their twelve hours. So live hundred years, they also. So even if you go there, ābrahma-bhuvanāl lokāḥ, or any planet, or any place, there must be death. Death you must have. But I am eternal. Why shall I accept death? That is intelligence. That information is given in Bhagavad-gītā, mad-dhāma gatvā punar janma na vidyate: "If you come to My place, My planet, then you will have no more to come back again to this mortal world." Mad-dhāma gatvā. Yad gatvā na nivartante tad dhāma paramaṁ mama [Bg. 15.6]. Where going, nobody returns. That is, actually, we want.
