<![CDATA[This study examines the Sumpah Kana Diri (SKD) manuscript through a philological approach focusing on codicology and textology. The research background originates from the condition of Sundanese manuscripts, which are often kept as private collections without proper conservation, making them vulnerable to damage and difficult to access. The purpose of this study is to reveal the physical characteristics of SKD and its textual content, which contains Islamic teachings, repentance, and cosmological symbols reflecting the philosophical thought of Sundanese society. The method applied is descriptive analysis with a single manuscript edition (codex unicus), since only one manuscript is available as the primary source. Codicological analysis shows that SKD was written in 1975 using Latin script, although it was originally in Arabic Pegon, with Sundanese, Arabic, Indonesian, and elements of Javanese languages, and presented in prose form. The manuscript’s physical condition has deteriorated, with faded ink and detached pages. Textological analysis reveals transcription errors such as substitution, omission, and addition, with substitution being the most dominant. The findings highlight SKD as a unique manuscript that holds not only religious but also philosophical and cosmological values. The conclusion emphasizes the role of philology as a bridge between Sundanese literary heritage and modern academic needs, while underlining the urgency of conservation and digitization for cultural preservation.]]>
