阿鼻地獄 (Skt, Pali; Jpn Abi-jigoku)
Also, hell of incessant suffering. The most terrible of the eight hot hells. The Avichi hell is located at the lowest level of the world of desire; it is often referred to as the great citadel of the Avichi hell because it is surrounded by seven solid iron walls that make it impossible for its inhabitants to escape. The Sanskrit word avichi was rendered into Chinese as "incessant," indicating that in this hell pain and suffering continue without interruption. "The flames of the Avichi hell" is an expression often used to refer to the sufferings of this hell, whose dwellers are consumed in flames. According to The Dharma Analysis Treasury, the Avichi hell is located twenty thousand yojanas beneath the ground, and its depth is twenty thousand yojanas. Accordingly, the bottom of this hell is located forty thousand yojanas beneath the ground. The hell measures up to eighty thousand yojanas in length and width. The Treatise on the Great Perfection of Wisdom says that one who commits any of the five cardinal sins or slanders the correct teaching is destined to be reborn in the Avichi hell.
