From Rigpa Wiki
The Sanskrit preta literally means 'departed'.
Chökyi Drakpa says:
- "The preta realm is destitute of food and drink, creating hunger and thirst. It is a grim place of rocks and charred tree stumps, where the words ‘food’, ‘drink’ or ‘comfort’ have never even been heard.... Since these pretas do not find anything to eat or drink for months and years on end, their bodies are emaciated like skeletons and they lack even the strength to stand.... The principal cause [for being reborn there] is being miserly or greedy for wealth and possessions."
- "[In a psychological sense, the hungry ghost realms] exist wherever people, though immensely rich, are never satisfied, craving to take over this company or that one, or endlessly playing out their greed in court cases."
Patrul Rinpoche speaks of two types of preta: those who live collectively and those who move through space. The former are further divided into three: 1) those suffering from external obscurations, 2) those suffering from internal obscurations, and 3) those suffering from specific obscurations. The pretas who move through space, he says, include spirits such as the tsen, gyalpo, shindré, jungpo, mamo, and theurang.
