The Shuo Wugoucheng jing shu 說無垢稱經疏 Commentary on the Vimalakīrtinirdeśasūtra by Ji 基 (632–682) is a systematic exposition of the concept of the Buddha-land. It not only comprehensively constructs the theoretical framework of the “Eight Gates and Fourfold Realm” but also addresses two key questions within the framework of “as the mind is pure, so is the Buddha-land 隨其心淨則佛土淨”—namely, what constitutes a Bodhisattva’s Pure Land and why Śāriputra perceived impurities in the Buddha-land. In this process, Ji extensively incorporates ideas from Yogācāra texts such as the Cheng weishi lun 成唯識論 Vijñapti-mātratā-siddhi and the Fodijing lun 佛地經論 Buddhabhūmisūtra-śāstra. He further advances the discourse by constructing the Pure Land from the perspectives of both the Buddha and sentient beings. In doing so, he presents a distinctly Yogācāra interpretation. Additionally, through his explanation of the causality of the Pure Land, he outlines a progression: cultivation of wisdom → purification of consciousness → purification of the land. Ji thereby embarks on a different interpretive path from Kumārajīva 鳩摩羅什 (344–413), Sengzhao 僧肇 (384–414), and others, highlighting his distinctive contribution and the unique significance of his Pure Land thought within the Yogācāra tradition and the Shuo Wugoucheng jing 說無垢稱經 Vimalakīrtinirdeśasūtra exegetical lineage.
