The Hungry Ghost, Preta, (Sanskrit: प्रेत, Standard Tibetan: ཡི་དྭགས་ yi dags)is a creature described in Buddhism, Hinduism, folklore, etc., lower on the karmic scale than humans, as a result of greed and hubris, they are destined to wander a very cold or very hot desert land, constantly hungry for disgusting things like human excrement or cadavers. Hungry ghosts are also said to arise when they are not remebered or honored by their ancestors.

Along with it, a dull red light from the Preta-loka, coming side by side with the Light of Wisdom, will also shine upon thee. Act so that thou shalt not be fond of it. Abandon attachment [and] weakness [for it]. At that time, through the influence of intense attachment, thou wilt become terrified by the dazzling red light, and wilt [wish to] flee from it. And thou wilt beget a fondness for that dull red light of the Preta-loka. At that time, be not afraid of the glorious, dazzling, trans­parent, radiant red light. Recognizing it as Wisdom, keeping thine intellect in the state of resignation, thou wilt merge [into it] inseparably and attain Buddhahood.
