This page from a "jigoku zoshi," or "hell scroll," depicts the part of "Great Hell of Screaming," one of the precincts of hell described in the Mindfulness of the Right Dharma Sutra. In Japan, this vision of hell was popularized by the Tendai monk Genshin (942-1017) in his work Ōjōyōshū or "The Essentials of Salvation." According to the Ōjōyōshū the key to avoiding the torments of hell lay in chanting the nembutsu, an appeal to the saving power of Amida Buddha.
This scroll was painted at the behest of emperor Go-shirakawa (1127-1192), but the artist and calligrapher are unknown.
Genshin himself described heaven and hell as follows:
Outside the four gates of this hell are sixteen separate places which are associated with this hell. The first is called the place of excrement. Here, it is said, there is intensely hot dung of the bitterest of taste, filled with maggots with snouts of indestructible hardness. The sinner here eats of the dung and all the assembled maggots swarm at once for food. They destroy the sinner's skin, devour his flesh and suck the marrow from his bones. People who at one time in the past killed birds or deer fall into this hell. Second is the place of the turning sword. It is said that iron walls ten yojanas in height surround it and that a terrible and intense fire constantly burns within. The fire possessed by man is like snow when compared to this. With the least of physical contact, the body is broken into pieces the size of mustard-seeds. Hot iron pours from above like a heavy rainfall, and in addition, there is a forest of swords, with blades of exceptional keenness, and these swords, too, fall like rain. The multitude of agonies is in such variety that it cannot be borne. Into this place fall those who have killed a living being with concupiscence. Third is the place of the burning vat. It is said that the sinner is seized and placed in an iron vat, and boiled as one would cook beans. Those who in the past have taken the life of a living creature, cooked it, and eaten of it, fall into this hell. Fourth is the place of many agonies. In this hell there are a trillion different- numberless tortures which cannot be explained in detail. Those who at some time in the past bound men with rope, beat men with sticks, drove men and forced them to make long journeys, threw men down steep places, tortured men with smoke, frightened small children, and in many other ways brought suffering to their fellow man, fall into this hell. Fifth is the place of darkness. It is said that here is pitch blackness that burns constantly with a dark flame. A powerful and intense wind blows against the adamantine mountains causing them to grind against each other and to destroy each other, so that the bodies of the sinners in between are broken into fragments like grains of sand. Then a hot wind arises which cuts like a sharply honed sword. To this place fall those who have covered the mouths and noses of sheep or who have placed turtles between two tiles and crushed them to death. Sixth is the place of joylessness. Here, it is said, is a great fire which burns intensely night and day. Birds, dogs, and foxes with flaming beaks whose intensely evil cries cause the sinner to feel the greatest of fear, come constantly to eat of the sinner, whose bones and flesh lie in great confusion. Hard-snouted maggots course about inside the bone and eat of the marrow. Those who once blew on shells, beat drums, made frightening sounds, or killed birds and animals fall to this hell. Seventh is the place of extreme agony. It is located beneath a precipitous cliff where a fire of iron burns continuously. People who once killed living creatures in a fit of debauchery descend to this hell....
The second division is the Pure Land towards which one must aspire. The rewards of Paradise are of endless merit. Should one speak of them for a hundred kalpas or even for a thousand kalpas, one would not finish describing them; should one count them or give examples of them, there would still be no way to know of them. At present, ten pleasures in praise of the Pure Land will be explained, and they are as but a single hair floating upon the great sea.
First is the pleasure of being welcomed by many saints. Second is the pleasure of the first opening of the lotus. Third is the pleasure of obtaining in one's own body the ubiquitous supernatural powers of a Buddha. Fourth is the pleasure of the realm of the five wonders. Fifth is the pleasure of everlasting enjoyment. Sixth is the pleasure of influencing others and introducing them to Buddhism. Seventh is the pleasure of assembling with the holy family. Eighth is the pleasure of beholding the Buddha and hearing the Law. Ninth is the pleasure of serving the Buddha according to the dictates of one's own heart. Tenth is the pleasure of progressing in the way of Buddhahood.
