Ksitigarbha said: Holy Mother, there are hells within the iron-enclosed mountain. There are eighteen hells in the great hell, and there are five hundred in them, with different names. There are thousands of hells in them, and they have different names. In the Infinite Prison, the prison city has a circumference of more than 80,000 miles. Its city is made of pure iron and is 10,000 miles high. Fire gathers on the city and there are few gaps. In its prison city, all prisons are connected and have different names. There is only one prison, called Wujian. Its circumference is eighteen thousand miles, and its walls are a thousand miles high. They are all surrounded by iron, and the fire from above penetrates the bottom, and the fire from below penetrates above. Iron snakes and iron dogs spit fire and gallop on the prison wall, running east and west.
