Later he moved to Mount Shicheng and established the Qiguang Temple. Sitting in tranquil meditation at the mountain gate, his mind wandered in the groves of dhyāna; eating tree fruits and drinking from mountain torrents, he set his aspirations freely on non-arising. He then annotated various scriptures such as the Ānāpānasmṛti and the Four Dhyānas, and wrote the 'Treatise on Wandering in the Mystery through Immediate Form', the 'Treatise on the Sage Not Debating Knowledge', the 'Purport of the Daoxing', and 'Admonitions for Learning the Way'. Following in the footsteps of Aśvaghoṣa and treading in the shadow of Nāgārjuna, his interpretations accorded with the fundamental Dharma and did not contradict the true nature of reality. In his later years he came out to Shanyin to lecture on the Vimalakīrti-nirdeśa-sūtra. Dun served as Dharma master and Xu Xun as the disputant. Whenever Dun elucidated an interpretation, the assembly all thought Xun had no way to raise an objection; whenever Xun raised an objection, they likewise thought Dun could no longer resolve it. Thus it went on to the end, neither side exhausting their arguments. All among the listeners believed they had fully grasped Dun's purport, but when turned back to explain it themselves, after two or three turns they fell into confusion.
