The Đinh family established the official religious organization in incorporating Taoists and Buddhists in an administrative hierarchy. Bộ Lĩnh awarded additional titles such as "Buddhist Priest Overseer" to Đại Việt’s ranking monks, and in 971 assigned Buddhism’s top position, that of great preceptor (đại sư) for reforming the Việt (khuông Việt), to the patriarch of the Vô Ngôn Thông sect, Ngô Chân Lưu, who occupied the post until his death forty years later. Another Buddhist priest, Trương Ma-ni and a Taoist priest, Đặng Huyền Quang were given the title "Buddhist Priest Overseer" ("Tăng lực đạo sĩ") and "Noble and Upright Majesty". Đinh Bộ Lĩnh also established shrines to the gods of earth and agriculture. In 973, Prince Đinh Liễn erected one hundred "ratanadhvaja " stone columns contain "Uṣṇīṣa Vijaya Dhāraṇī" sutras (written in Classical Chinese) in order to generate merits to help liberate the spirit of his deceased brother. Liễn established another hundred tantric pillars in 979, aiming to gain a healthy perpetuation of the kingdom. Archaeological efforts from 1963 to 1987 have recovered 20 of those stone pillars.
