大方廣佛華嚴經疏 3.14

3.14

Fourth, the treatises and commentaries: briefly four are cited: First, after Nāgārjuna obtained the lower recension, he composed the Da busiyi lun, also in a hundred thousand verses, which was fully transmitted in the Western Regions. In this land, the Shizhu piposha lun in sixteen fascicles is that treatise's commentary on the first two stages of the ten stages. Second, Bodhisattva Vasubandhu composed the Shidi lun to comment on the chapter 'Ten Stages'; in the Wei dynasty, Tripiṭaka Master Ratnamati and Bodhiruci each translated a version, and Senior Vinaya Master Guangtong petitioned the throne to have the two Tripiṭaka Masters collate them into a single text of twelve fascicles, which is the version transmitted today. Third, Liu Qianzhi of the Northern Qi had an extraordinary spiritual resonance on Mount Qingliang and composed a treatise in six hundred fascicles, fully commenting on the entire sūtra. Fourth, during the Later Wei, the monk Lingbian carried this sūtra on his head on Mount Wutai and practiced the path for one year, whereupon he awakened to its mysterious purport and composed a treatise in one hundred fascicles, which is also transmitted in the world.
