TIME: In your book [Zhuan ] you talk about people levitating off the ground but you say that they should not show other people. Why is that?
Li: It is the same principle that Western gods in paradise should not be seen by ordinary mortals because they cannot understand its meaning.
TIME: Have you seen human beings levitate off the ground?
Li: I have known too many.
TIME: Can you describe any that you have known?
Li: David Copperfield. He can levitate and he did it during performances
