What is your name for the hungry ghosts?

Every religion, philosophy, and system of mysticism has a name for what the Buddhists call hungry ghosts. Hungry ghosts are beings eternally trapped by samsara – the Hell of the senses – where they are driven eternally by the need to devour, never sated, never ceasing in their desperate, blind pursuit of material things. In Kaballism, the empty husk which remains when all meaning and spirit has vanished is called Qlippoth, a sort of energy vampire which seeks fruitlessly to fill its internal void. In “Heart of Darkness,” Joseph Conrad refers to them as the “hollow men,” through whom you could punch a finger to find only a light coating of dust.
