An early manuscript version, titled "Twenty-One Hymns to the Rescuer Mother of Buddhas" (二十一種救度佛母贊), described as an "Imperially commissioned translation of the hymn to the rescuer mother of Buddhas ... in Manchu, Tibetan, Mongolian, and Chinese scripts", was created in the late 18th century by calligrapher Yongrong 永瑢 (1744–1790). It is held by the National Library of China.
