7.35

Also, the Da faju jing says: The Buddha said: “All sentient beings are assigned names according to their physical species, such as birds and sparrows. But among hungry ghost sentient beings, there are no fixed, distinct names. Do not say that devas are fixed as devas, humans are fixed as humans, and hungry ghosts are fixed as hungry ghosts. Just as there are various names for a single thing, or various names for a single person, or various names for devas down to hungry ghosts and animals, so it is in this case too. Moreover, many hungry ghosts have no name at all, and in the snap of a finger they transform their bodies into various shapes. How could one call them by name? Because the causes and conditions of their evil karma are not yet exhausted, in a single thought-moment they transform into various bodies.”
