Many within the movement regard the "Book of Veles" as a holy text, and as a genuine historical document. Some Rodnovers take their cosmology, ethical system, and ritual practices from the "Book". The fact that many scholars outspokenly reject the "Book" as a modern, twentieth-century composition has added to the allure that the text has for many Rodnovers. According to them, such criticism is an attempt to "suppress knowledge" carried forward either by Soviet-style scientism or by "Judaic cosmopolitan" forces. Other modern literary works that have influenced the movement, albeit on a smaller scale, include "The Songs of the Bird Gamayon", "Koliada's Book of Stars", "The Song of the Victory on Jewish Khazaria by Sviatoslav the Brave" or "The Rigveda of Kiev".
