This article examines a cluster of five idiosyncratic technical terms — Ren-Kha, Sefi-Ra, Kap-Ele, Ked-Ur, and Ain-Sakh — found in an unpublished early-twentieth-century Russian esoteric manuscript provisionally titled Conversations of the Old Priest. Drawing on six years of research into the manuscript, and on systematic cross-referencing against the major published corpora of Russian and Western esotericism (Martinism, Theosophy, Christian and Hermetic Kabbalah, and academic Egyptology), the study argues that this vocabulary is unattested outside the manuscript itself. Rather than treating this absence as an obstacle to research, the article proposes that the lexicon's isolation is itself significant evidence: it suggests a private, non-disseminated transmission of doctrine, and offers a methodological criterion — the "terminological fingerprint" — for future comparative work on the manuscript's authorship and milieu.
