Daoism is known through an unusually layered, internally diverse evidentiary record in which textual authority, ritual practice, and lineage transmission interlock but do not converge into a single canon. Its written sources range from early classics (Daodejing, Zhuangzi)—texts later elevated into religious frameworks—to expansive revelation and liturgical corpora (Celestial Masters, Shangqing, Lingbao) and the Daoist Canon (Daozang), a bibliographic system whose inclusions reflect institutional power rather than universal acceptance. Commentaries, inner-alchemy manuals, ritual handbooks, morality books, and hagiographies often shape lived Daoism as much as, or more than, foundational texts, yet authorship and redaction are frequently opaque because “authorship” commonly functions as lineage legitimacy. Oral performance—chanting, recitation, apprenticeship teaching, and master–disciple genealogies—preserves ritual competence but varies regionally and is vulnerable to disruption under state regulation. Material and epigraphic evidence anchors Daoism in temples, sacred mountains, and stele networks, while systematically underrepresenting household rites and perishable talismanic practice. Historical records, gazetteers, temple archives, and ethnography allow triangulation, but the central analytic requirement is strict stratum-tagging: philosophical, institutional-liturgical, and local-performative Daoism must be dated and distinguished to avoid false continuity and category errors.
