Jaya-gopāla: Is past, present and future, in the material sense, a perverted reflection of the same...
Prabhupāda: Yes, past, future, present is according to the different kinds of relativity. That is a scientific proof. Professor Einstein has proved it. Just like your past is not past of Brahmā. Your present is not the present of an ant. So past, present, future-time is eternal. It is according to the different dimension of body relativity. Time is eternal. Just like a small ant. In twenty-four hours he has twenty-four times past, present and future. In the sputnik, in the Russian sputnik, circumambulated round this earth in one hour, twenty-five minutes, or something like that. They, I mean to say, went round the earth for twenty-five times. That means within one hour, twenty-five minutes, the sputnik man saw twenty-five times day and night. So in the higher atmosphere the past end present is different. So this past, present, future is relative according to your body, according to circumstances. Actually, there is no past, present, future. Everything is eternal. You are eternal, nityo śāśvato 'yaṁ na hanyate hanyamāne śarīre (BG 2.20). You do not die. Therefore... The people do not know that I am eternal. What is my eternal engagement? What is my eternal life? They're simply captivated on the spot life: "I am American," "I am Indian," "I am this," "I am that." That's all. This is ignorance. So one has to search out this eternal engagement with Kṛṣṇa. Then he'll be happy.
