The mathematician W. R. Ball reports the following legend: In a temple of Benares, there is a dome under which a plate of bronze marks the center of the world. On this plate, there are three vertical stems of one cubit height. During the creation of the world, God placed on one of the stems 64 discs of gold of different sizes, the largest at the basis, the others going decreasing. In top, the smallest disc. This accumulation is the tower of Brahma. Night and day, without stop, the priests relay to transfer the discs from a stem to another. Only one disc must be take at once and it is forbidden to place a disc on another of lower diameter. When the 64 discs will be transferred from the tower of Braham to an other stem, the temple and the Universe will crumble. This will be the end of the world.
