Avitchi

Avitchi, also transliterated Avichi, (devanāgarī: अवीचि, avīci) is a Sanskrit and Pali word used in Buddhism meaning "without waves". It refers to the lowest level of "hell" (naraka), into which the dead who have committed grave misdeeds may be reborn. Although in Buddhism Hells are temporary, Avichi is often regarded as a place of no return, where beings languish eternally.

[[Helena Petrovna Blavatsky|Mme. Blavatsky defined it as follows:

Avîtchi (Sk.). A state: not necessarily after death only or between two births, for it can take place on earth as well. Lit., “uninterrupted hell”. The last of the eight hells, we are told, “where the culprit, die and are reborn without interruption--yet not without hope of final redemption”. This is because Avitchi is another name for Myalba (our earth) and also a state to which some soulless men are condemned on this physical plane.
