Avichi avici (Sanskrit) [from a not + vichi waves, pleasure]; “Not funny”. "A generalized term for places of evil realizations, which is a state of 'punishment' in itself; like Dante's Hell; where the will for evil, and the unsatisfied evil longings for pure selfishness, find their chance for expansion -- and final extinction of the entity itself (Gehenna). Avichi has many degrees or grades. Nature has all things in her; if she has heavens where good and true men find rest and peace and bliss, so has she other spheres and states where gravitate those who must find an outlet for the evil passions burning within. They, at the end of their avichi, go to pieces and are ground over and over, and vanish away finally like a shadow before the sunlight in the air -- ground over in Nature's laboratory" .
Avichi is a state of mind, not a locality per se; nevertheless, an entity, whatever state it may be in, must have location, and consequently so far as the human race is concerned, avichi is Myalba, our earth in certain of its lowest aspects. Beings entirely in avichi are born and reborn uninterruptedly, with scarcely intermissions of time periods in order to be remodelled entirely, while being reborn as new identities. As long as the entity does not sink by attraction into Death, it still has within it the possibility of regaining its foothold on the ascending evolutionary ladder and rising again. Rare indeed are those who succeed in so rising, but the case is not absolutely hopeless. Avichi is comparable with Tartaros, the lowest section of Hades.
