Prabhupāda: Foolish people, they are ignorant, but there is next life, and this life is preparation for next life. That they do not know. The modern education, universities, they're completely in darkness about this simple knowledge. We are changing body every moment—that's a medical science—and after changing this body, we'll have to accept another body.
How we are going to accept that body, what kind of body, this can be also known. Just like one is being educated, when he passes his examination one can understand that he's going to be engineer or a medical practitioner. Similarly, in this life you can prepare yourself to become something next life.
Barbara (Bob's fiancee): Can we decide what we want to be in our next life?
Prabhupāda: Yes, you can decide. Just like we have decided next life we are going to Kṛṣṇa. This is our decision, back to home, back to Godhead. Just like you become educated after decision that you are going to be engineer, you are going to be medical practitioner, and in that objective you prepare yourself, educate yourself.
Similarly, you can decide what you are going to do next life. If you don't decide, then material nature will decide. Just like a boy who is not nicely educated, without any future objective, the government will decide. If he's a criminal, then government will decide, "Go to jail," and if he's nicely educated, the government will decide, "You take this job."
