There is a story in Introduction to the Middle Way (Madhyamakavatara): Once in a kingdom there was a very good fortune teller. He told the king it would rain seven days later and the rain water would be toxic. Whoever drank the water would become insane. After hearing this, the king covered his well but didn’t let others know. Seven days later, it rained as prophesized. Everyone in the kingdom drank the rain water and lost their minds except the king and a few people around him. As only these few were not affected, all the others turned around to accuse them of being mad. The situation became so unbearable that the king finally gave in, drank the rain water and became crazy like all the others.
