How does Lama Norbu describe re-incarnation to Dean in Bernardo Bertolucci's movie Little Buddha?

Lama Norbu explains the concenpt of re-incarnation with an
analogy with some tea in a cup. He says that in Tibet they think of the mind and the
body in terms of the contents and the container. While he says this the Lama is pouring
some tea in a white cup. As he finishes his sentence, he smashes the cup (framed in a
close-up by the camera) on the table. The Lama then comments that the cup is no longer a
cup but that the tea is always tea even though it's no longer in the cup but has spilled
on the table and on the floor. "It moves from one container to another but it's still
tea, like the mind . . . it moves from one body to the other but it is still
mind".
