Overview
In describing the terrifying mechanics of cosmic justice, the Buddha detailed the structural architecture of the Great Hell (Mahaniraya). He listed four immutable physical torments or walls that systematically enclose the mind of the wrongdoer, ensuring that escape is completely impossible until the unwholesome kamma is entirely exhausted.
The List
- Cattāro Dvārā - The Four Iron Doors: The hell is constructed as a massive cube featuring four distinct, reinforced iron gates situated at the four compass directions.
- Ayopākāra - The Iron Walls: The entire realm is completely surrounded by towering walls made of blazing, glowing iron, trapping the heat inside.
- Ayomayā Chadanā - The Iron Roof: The ceiling of the realm is a solid plate of burning, incandescent iron that prevents any upward flight or escape.
- Ayomayā Bhūmi - The Iron Floor: The ground is composed entirely of red-hot, glowing iron sheets from which fierce flames shoot up, ensuring continuous, excruciating physical contact.
