Bai Longma (White Dragon Horse)

Within the narrative world of Journey to the West (a 16th-century Chinese novel), the being is presented as a dragon who assumes the form or role of a horse to serve the pilgrim monk Tang Sanzang. By the end of the novel the character is ritually elevated within the story's Buddhist-inflected celestial ordering, receiving the title Babu Tianlong Guangli Bodhisattva. The provided sources do not supply an extended origin myth beyond this narrative role and subsequent ordination.

Sources identify the figure by the compound label 'White Dragon Horse' (白龍馬), indicating a dragon being appearing or conceptualized as a white horse or a dragon in horse form. The available summaries do not provide further detailed physical description.

Documented behavior in the sources is primarily service as Tang Sanzang's steed throughout the pilgrimage in Journey to the West. The character is also capable of spiritual promotion within the novel's Buddhist/folk celestial hierarchy, culminating in ordination to a bodhisattva-style office. No other specific powers or abilities are enumerated in the provided excerpts.
