Vietnamese Buddhism gained an apex during the medieval period. The king, the court, and society were deeply Buddhist. According to Đinh Liễn's Ratnaketu Dhāraṇī inscriptions (c. 973), Mahayana Buddhism and some elements of Tantric Buddhism were promoted by the emperor and the royals, who devoutly Buddhists. Mahayana sutras were inscribed along with the Prince's speech on these pillars. The inscription of Lê Đại Hành (c. 995) however mentioned Thiền Buddhism as the royal religion. By the early 11th century, Mahayana, Hinduism, folk beliefs, and spiritual worship was fused and formed into a new religion by Ly royals, who frequently performed Buddhist rituals, blood oaths, and prayed for spiritual deities. This syncretic religion, dubbed as "Ly dynasty religion" by Taylor, embraces the amalgamating worship of Buddhism, Indian Buddhist deities Indra and Brahma, and Cham folk legend Lady Po Nagar. The Lý dynasty religion later was absorbed into Vietnamese folk religion. The emperors built temples and statues delicate for Indra and Brahma in 1016, 1057, and 1134, along with temples for Vietnamese legends. At the funeral, the emperor’s body was put on a pyre to be burned, according to Buddhist tradition. The main characteristics of Vietnamese Buddhists were largely influenced by Chinese Chan Buddhists. A temple inscription dated from 1226 in Hanoi describes a Vietnamese Buddhist altar: "the Buddha statue was flanked by an Apsara, one of the Hindu water and cloud nymphs, and a Bodhisattva with a clenched fist. Before the altar stood statues of a Guardian of the Dharma flanked by Mỹ Âm, king of the Gandharvas, mythical musician husbands of the Apsaras, and Kauṇḍinya, the Buddha’s leading early disciple."
