Preta
From Wikipedia, the free encyclopedia
Preta (Sanskrit) or Peta (Pāli), Tibetan yi.dvags, is the name for a type of supernatural being described in Buddhist, Hindu and Jain texts that undergoes more than human suffering, particularly an extreme degree of hunger and thirst.
[edit] Etymology
The word preta is derived from Sanskrit pra ita, literally "(one who is) gone forth" and originally referred to any of the spirits of the deceased - compare the English use of "the departed". It later became confined to a type of unhappy or malevolent spirit, and as such it was taken up by Buddhists to describe one of several possible states of postmortem existence.
[edit] Description
Pretas are invisible to the human eye, but some believe they can be discerned by humans in certain mental states. They are described as human-like, but with sunken, mummified skin, narrow limbs, enormously distended bellies and long, thin necks. This appearance is a metaphor for their mental situation: they have enormous appetites, signified by their gigantic bellies, but a very limited ability to satisfy those appetites, symbolized by their slender necks.
Pretas dwell in the waste and desert places of the earth, and vary in situation according to their past karma. Some of them can eat a little, but find it very difficult to find food or drink. Others can find food and drink, but find it very difficult to swallow. Others find that the food they eat seems to burst into flames as they swallow it. Others, if they see something edible or drinkable and desire it, it withers or dries up before their eyes. As a result, they are always hungry.
In addition to hunger, Pretas suffer from immoderate heat and cold; they find that even the moon scorches them in the summer, while the sun freezes them in the winter.
The sufferings of the Pretas often resemble those of the dwellers in Naraka, and the two types of being are easily confused. The simplest distinction is that beings in Naraka are confined to their subterranean world, while the Pretas are free to move about.
