The Narakas are the realms of suffering that equate to the Christian hell or, more accurately, to purgatory . If a person is born into one of these realms as a result of bad karma , this is not a permanent punishment - he or she may well be reborn into one of the higher worlds in the next life . Watched over by Yama , judge of the world, the Narakas are not only physical places but also states of consciousness – and symbols of the suffering that can take place during life, as well as after death .
In the early Vedic tradition , the death god Yama kept two dogs, SYama the Black and Sabala the Spotted, to bring and hold souls in the Purgatory-like afterlife called Naraka. Even the Norse god Odin kept a pair of wolves, Geri and Freki.
