Hungry ghosts, "The Treatise on Bhasha" says: "The ghost is afraid, it is said to be cowardly and fearful, and it is powerful, which can make him afraid of its might, and he also wants to be a famous ghost, and he is called a hungry ghost, and he always wants to eat and drink from others in order to survive." ”
In the Dharma Recitation Sutra: Hungry Ghosts, it says: "Knowing the karma and retribution, there are countless kinds of hungry ghosts, and they use wisdom to smell wisdom, and glance at the thirty-six kinds of hungry ghosts, all of which are born in other places because of the causes of greed and jealousy, and they create all kinds of karma and do all kinds of deeds with all kinds of hearts, and all kinds of dwellings, all kinds of hunger and thirst burn their bodies. "These are the thirty-six kinds of ghosts that are born in the ghost path because of the causes of greed and jealousy, all kinds of karma, all kinds of deeds, all kinds of hunger and thirst, and the karma they create and the suffering they suffer burns themselves.
Ghosts and sentient beings are scattered everywhere, like our people's homes, streets and alleys, and graves, there are ghosts and gods, and there are no empty ones, and ghosts and gods are based on the name of the person, according to the person, according to the tree for the tree, according to the river for the river, all the trees are as small as the axle of the car have ghosts and gods to rely on.
The blessed are the gods of the mountains, the forests, and the gods of the mountains, and the gods of the trees, but the unblessed ones are the impure dwellings, and are often scourged, driven away, filled in rivers and seas, and suffer immeasurably, and are flattering.
The ghost path is due to the five reverses and ten evils of the pretentious quality, and the ghost body is hungry.
