Those who happen to know the difference between the true and evil teachings of the Buddha will be abandoned by all the people in the country. The protective deities of the land, without tasting the savior of the True Dharma, will lose their divine powers to benefit the people until in the end they will all abandon this country for some other lands. Taking advantage of the situation, evil demons will grow rampant throughout the land, causing the earth to quake, evil winds to blow, the entire country to suffer, and staple grains to fail to ripen. As a result a famine and water shortage will occur, evil devils will enter the bodies of the people to suck up their energy. This is called an epidemic. People all will lose the virtuous mind, and the majority of them will fall into evil realms. This solely stems from putting faith in provisional teachings preached by “evil friends.”
