"Whatever state of being one remembers when he quits his body, that state he will attain without fail."
Dr. Singh.  Śrīla Prabhupāda, if our next body is always achieved by our consciousness in this life, how is it that I cannot remember my previous life?
Śrīla Prabhupāda.  Do you remember everything you did last year, or even yesterday?
Dr. Singh , No, I don't...
Śrīla Prabhupāda . That is your nature: you forget..
Dr. Singh ,  Some  things.,
Śrīla Prabhupāda . And somebody forgets more than others. But we all forget.
Dr. Singh.  Is that a principle of material nature?
Śrīla Prabhupāda.  Yes. It is something like stealing. Somebody is a pickpocket and somebody is a bank robber, but both of them are stealing.
Dr. Singh.  When we dream, are we being carried away by the subtle elements?
Śrīla Prabhupāda . You are being carried away by nature. Krṣṇa says in  Bhagavad-gītā  (3.27):

"The bewildered spirit soul, under the influence of the three modes of material nature, thinks himself to be the doer of activities that are in actuality carried out by nature." We forget our real identity because we are under the grip of material nature. The first lesson in spiritual life is that we are not these bodies, but eternal spirit souls. Once you were a child. Now you are a grown man. Where is your childhood body? That body does not exist, but you still exist because you are eternal. The circumstantial body has changed, but  you  have not changed. This is the proof of eternality. You remember that you did certain things yesterday and certain things today, but you forget other things. Your body of yesterday is not today's body. Do you admit it or not? You cannot say that today is the thirteenth of May, 1973. You cannot say that today is yesterday. The thirteenth was yesterday. The day has changed. But  you  remember yesterday; and that  remembrance  is evidence of your eternality. The body has changed, but you remember it; therefore you are eternal, although the body is temporary. This proof is very simple. Even a child can understand it. Is it difficult
Changing Bodiess
Dr. Singh , People want more proof.
Śrīla Prabhupāda.  What more is required? The eternality of the soul is a simple fact. I am an eternal soul. My body is changing, but I am not changing. For example, I am now an old man. Sometimes I think, "Oh, I used to jump and play, but now I cannot jump because my body has
