At one time, there were some vampires and Yaksha ghosts who often caught people to suck their blood to sustain themselves. They didn’t eat the five grains. In that country, the people were forced to keep the ten precepts, ten benevolent precepts, and keep their body, speech and mind pure, so the evil spirits dared not to get close to them and suck their blood. So these spirits were very hungry and famished. They became so skinny and boney that they were about to die. At that time, five spirits went to report to the king, saying, “Your Majesty, spirits like us feed on human’s energy and blood in order to survive. Now you ask your people to keep the ten benevolent precepts. Everyone is practicing spiritually with you and each one of them has guards and angels around to protect them. We dare not to catch them and suck their blood. We have been hungry for a long time, and we cannot bear it anymore. Now we are waiting for death. You cultivate compassion. Why don’t you take pity on us? Why don’t you love us and care about us?” They were right. If he protected his people, these spirits would die of hunger. What to do?
