Avici Hell; 無間地獄 (昧喔那若梅巴); Tibetan: མེ་བའི་རྣལ་འབྱོར་མེད་པ། (meywe naljorme pa);  Wylie: me ba’i rnal ‘byor med pa; Sanskrit: Avici;

Avici, often translated as “uninterrupted” or “incessant,” is considered the lowest and most terrible of the hell realms in Buddhist cosmology. Beings born into this hell endure continuous and extreme suffering without any pause. It is typically reserved for those who have committed grave offenses such as matricide, patricide, killing an arhat, causing schism in the sangha, or shedding the blood of a Buddha. Liberation from this realm is extremely difficult, but not impossible through the power of merit and spiritual practice performed by oneself or others on their behalf.

無間地獄是佛教宇宙觀中最底層、最恐怖的地獄，又稱「阿鼻地獄」。生於此地獄的眾生，將遭受極其劇烈且毫無間斷的痛苦，故名「無間」。此地獄通常為犯下五逆重罪者所墮之處，例如弒母、弒父、殺害阿羅漢、破和合僧或出佛身血等。然而，通過自身修行功德或他人代為回向，仍有可能從此地獄解脫。
