Interview -- March 9, 1968, San Francisco:

Prabhupāda: Unfortunately, the people, they do not believe in the next life. Although in every day affair they are experiencing that "I am eternal. I can remember the days of my childhood. I can remember the days of my youthhood, my boyhood, and I am still working. That means I am continuously there although my body in different ways have changed." So it is a fact that even after changing this body, you will have another body. Just like you are sitting in this room. Now, if you vacate this room, that does not mean you are finished. You have gone in some other room. So this is a great science. And people are neglecting this science. They have no, I mean to say, information. There are so many departments in universities, technological, medical, engineering, but where is the department to know or understand what is this life, what is God, what is our relationship? So this is not very good civilization. So there is life after this life. Just like progressive life, a child is progressing to youthhood, the youth is aspiring to become a big man, important man. As in this life there is progressive life, similarly, life after life, there is also progress. There are different grades of life. So we get information from authoritative books that there are 8,400,000's of different grades of life, and there are 900,000's of aquatic life, two million species of plants and trees, about eleven hundred thousand species of life of birds, three million types of species of beast, and 400,000 species of this human body. Out of that 400,000's, different kinds of human bodies, the civilized body is a great boon. At that time we can make further progress.
