Once upon a time there was a king in India. An astrologer told him: “Whoever shall drink the rain which falls seven days from now shall go mad.” So the king covered his well, that none of the water might enter it. All of his subjects, however, drank the water, and went mad, while the king alone remained sane. The king could no longer understand what his subjects thought and did, nor could his subjects understand what he thought and did. All of them shouted, “The king is mad! The king is mad!” Thus, seeing no other choice, the king drank the water, too.
