Sikhism is documented through a highly text-centered yet historically layered evidentiary record, distinguished by the central, institutional authority of the Guru Granth Sahib alongside a surrounding field of contested and graded sources. Scripture functions not only as doctrinal reference but as living authority through enthronement, recitation, and daily liturgical use in the gurdwara, giving Sikh textual evidence an unusual degree of stability compared to many South Asian traditions. At the same time, adjacent corpora—the Dasam Granth, rehat literature, janamsakhis, historical chronicles, and institutional documents—introduce stratification, debate, and later codification that must be carefully separated from the core canon. Oral transmission through kirtan, kathā, and community storytelling reinforces textual authority while amplifying hagiographic and political emphases. Material, epigraphic, and archival records strongly document gurdwara networks, Khalsa identity, and Sikh polities, yet often reflect commemorative memory as much as contemporaneous practice. As a result, Sikh evidence requires disciplined source-layering: a stable scriptural core must be analytically distinguished from evolving narrative, institutional, and political frames.
