Preta (Hungry Ghost)

Across the cited sources Pretas are presented not as a single origin myth but as a karmic rebirth-state within Indic and East Asian cosmologies: beings reborn as Pretas suffer from intensified appetites (craving) and an inability to assuage them, consequences of past actions and attachment. The Mulian narrative (an elaboration of the Yulanpen Sutra) provides a ritual-historical working example in which a filial practitioner (Mulian) petitions the Buddha and organizes offerings and monastic participation to transfer merit and relieve his mother's suffering—linking moral conduct, filial duty, and remedial ritual to the condition and remediation of Pretas (Wikipedia: Preta; Mulian Rescues His Mother).

The supplied sources emphasize the experiential suffering of Pretas rather than offering a single, consistent canonical physical description. Modern summaries and popular accounts often depict hungry-ghost motifs (emaciation, inability to ingest food, grotesque appetites), but the primary materials in the supplied corpus foreground the being's extreme hunger and thirst and its role as a model of postmortem suffering rather than a standardized iconographic anatomy. Consequently, descriptions in the sources prioritize the condition (insatiable craving) and moral significance over a single fixed physical form.

Pretas are characterized primarily by the behavioral condition of unending hunger and thirst that cannot be satisfied. Sources describe their suffering as greater than that of humans, centered on extreme appetites; Buddhist didactic texts situate this condition as the fruit of demeritorious actions (akusala), making the Preta both a consequence of karma and a pedagogical example. Secondary materials summarize folkloric motifs—fixation on particular substances or corrupt desires producing specific cravings—but the supplied primary overview emphasizes the general incapacity to be sated and the moral causation rather than a catalogue of supernatural powers or varied abilities.
