Geba is a syllabic script for the Naxi language. It is called ¹Ggo¹baw in Naxi, adapted as Geba, 哥巴, in Chinese. Some glyphs resemble the Yi script, and some appear to be adaptations of Chinese characters. Geba is only used to transcribe mantras, and there are few texts, though it is sometimes used to annotate dongba pictographs.
