The Falun Gong teacher gladly gave her a book on the Falun Dafa (they buy in bulk, I believe). The book was very lucidly written/translated and, right at the beginning, solved an old mystery for me.
How David Copperfield walked through the Great Wall of China.
I saw the video in Madras in 1990 and it's totally amazing. I recall it as if I saw it y'day. If you haven't seen it, it goes as follows:
DC is on one side of the Great Wall, with a platform made of tubular steel frame resting against it. Think of a high-chair propped against the Great Wall and you get the picture. A white sheet is wrapped against the upper part of the frame and lit from behind. After a while, you see the silhouette of DC disappearing into the Great Wall. The sheet is whipped open and no one's there. The frame is then taken to the other side (the wall is at least 25 feet thick there) and set in place. The same white cloth is cupped against the Great Wall and you see the head of DC trying to wriggle out, but going back inside! So the sheet is again wrapped against the upper part of the frame and, with the backlight, you see the form of DC floating in horizontally and then standing up. At that point, the white sheet is removed with a flourish and you see DC standing there, all smiles.
The book says: (page 4)
David Copperfield, a magician in the US, is a master of supernormal abilities, and he once performed the feat of walking through the Great Wall of China. When he was about to pass through the Wall, he used a white cloth as a cover, applied himself to the Wall, and then proceeded to go through it. Why did he do that? That way, many people would consider it a magic performance. It had to be done that way, for he knew that there were many people with great supernormal abilities in China. He was afraid of interference from them, so he covered himself before he went in. When coming out, he stuck one hand out, raised the cloth, and walked out.
