Buddhist mythology [SEP] Kings, saints and gods
Buddhist traditions contain large numbers of stories and spiritual narratives in addition to the above. These are often simple moral fables, similar to Jātakas. In some cases, mythic complexes can be discerned that have no counterparts in the orthodox texts, but are found widely in popular culture. Various figures other than the Buddha appear in these myths, including Buddhist kings, important monastics and saints, as well as heavenly beings or gods (devas). Indian kings feature in many Buddhist stories and myths. The earliest texts speak of various kings paying respects to the Buddha such as Pasenadi of Kosala and Bimbisara of Magadha.
