There is an ancient story in the East which tells that there was a wall of mystery. The tradition was that whenever anyone tried to climb upon the wall to look at the other side, instead of coming back he smiled and jumped over and never came back again. So the people of that country became very curious to know what mystery lay behind that wall. They thought they would arrange something so as to pull the person back when he looked at the other side of the wall and wished to go there. When the next person tried to climb upon the wall, curious to see what was on the other side, the people who saw him climb put seven chains on his feet and held him so that he would not go over. When he looked at the other side he too was delighted with what he saw and he smiled. Those standing at their side, curious to know what he had to say, pulled him back, but, to their great disappointment, when he came back they found that he had lost his speech.
