In the first year of Yuanhe, an edict appointed Śramaṇa Duanfu to oversee the clerical affairs of the Left Street and manage the Buddhist rituals in the inner palace, and Śramaṇa Lingsui to oversee the clerical affairs of the Right Street (the Buddhist registry began with Master Faqin of the Yao Qin). Śramaṇa Zhixuan was summoned by edict to enter the palace to discuss the Way, and was bestowed the title National Preceptor Wuda. Xuan was able to compose poetry at the age of five, left home to become a novice, and at fourteen lectured on the Mahāparinirvāṇa Sūtra. Li Shangyin presented him with a poem that read: 'At fourteen, the novice can lecture on the sūtra; / Others of the master's age only carry the water-bottle. / When the novice expounds the Dharma, the śramaṇas listen; / It lies not in advanced age, but in spiritual nature.' The Uyghurs sent an envoy, who came to court together with deceptive Manichaeans.
