The Hungry Ghost Realm
The dimension of hungry ghosts realm is of phantom-like creatures representing a mix craving and hatred. Tormented by unfulfilled cravings and insatiably demanding of impossible satisfactions, they are beings with having terrible emptiness within themselves who cannot see the impossibility of getting something that has already passed away.
Their ghost-like state represents their attachment to their past. While being impossibly hungry and thirsty, they cannot eat or drink without causing themselves terrible pain or indigestion. Their long thin throats are so raw and narrow that swallowing produces unbearable burning.
Their bloated bellies are also unable to digest nourishment.
