In Buddhism, Avīci (Sanskrit and Pali for "without waves" — Japanese and Chinese: 無間地獄, Wújiàn dìyù and
阿鼻地獄, Ābí dìyù) or Avichi, is the lowest Level of the Naraka or "Hell" realm, into which the dead who have
committed grave misdeeds may be reborn. It is said to be a cube 20,000 yojanas (120,000 to 300,000 km)
to a side, buried deep underneath the earth. Avīci is often translated into English as the "NON-returning"
Hell, due to the idea that those beings which have been sent there languish there eternally. The other Hells
function more like Purgatory, where after perhaps a few eons of suffering, the being might be reborn as
some sort of lowly life-form, in a somewhat less horrible place; but, the beings in Avīci Hell are thought to
be hopeless for any respite.
