Diting

Sources record a folkloric/hagiographic variant in which Diting is the transformed form of a white dog that accompanied Kṣitigarbha in the bodhisattva's human/prior-life biography (the Silla/ Kim Gyo-gak legend). According to that legend, when Kṣitigarbha became enlightened the dog became Diting and thereafter served as a guardian of hell; this account is presented as a legendary variant rather than as a doctrinal canonical origin.

Descriptions in the available sources portray Diting as a composite creature combining features of multiple auspicious beasts: the head of a tiger, the body of a dragon, the tail of a lion, a single horn, ears like a dog, and feet like a qilin. Modern fictional depictions vary, but the primary assembled descriptions emphasize this hybrid morphology; some traditions and retellings identify a prior form as a white dog that was transformed.

Source accounts attribute to Diting exceptional auditory and perceptual faculties — its single horn is interpreted in some sources as capable of receiving information across the universe and its hound-like ears are metaphorically described as transmitting the ability to distinguish good from bad. Diting is said to be able to distinguish truth from falsehood and to identify creatures; it is also described as capable of using its horn defensively or offensively. Narratively, Diting functions as the attendant guardian of Kṣitigarbha and in legends (including a Journey to the West episode) demonstrates practical moral judgment and deference to higher authority when deciding whether to act on its discernment.
