The Hell of Great Burning Heat, the seventh of the eight major hells, is located beneath the Hell of Burning Heat, and its length and breadth are the same as the Hell of Burning Heat. However, the torment in this hell is ten times more severe than all the torments of the six hells mentioned above combined. The life span of sinners in this hell is half the length of a medium kalpa.

Those who commit the sin of violating a nun who observes the precept of purity, in addition to the grave sins of killing, stealing, adultery, drinking intoxicants, lying and harboring a false view will fall into this hell. Buddhist monks violating women who observe the precept against adultery by making them drunk with sake or fooling them with the gift of property or money will fall into this hell. Many Buddhist monks today are committing this grave sin.

Referring to this, the Great Compassion Sūtra preaches: “In the Latter Age of Degeneration many men and women in the laity are being reborn in heaven, but many priests and nuns are falling into hell.” People with conscience should be ashamed of themselves.
