《金刚经》在印度有唯识家（无著、世亲）的论释。传入中国，三论、天台、贤首、唯识各宗都有注疏；然而中国佛教深受真常系大乘的影响，各宗表面上阐扬《金刚经》，实际上阐扬常住佛性和如来藏。又在三教合流环境下，明清以来，三教九流都来注解《金刚经》，杂合浓厚的真常理论和儒道信仰。(Diamond Sutra has interpretation by the East Asian Yogācāra (Asanga and Vasubandhu) in India.After its introduction to China, East Asian Mādhyamaka, Tiantai, Huayan and East Asian Yogācāra had their own commentaries; however as Chinese Buddhism has been deeply influenced by tathāgata-garbha branch of the Mahayana, different schools ostensibly endorse the Diamond Sutra but more aligned to Tathāgatagarbha sūtras which believes in the eternity of the Buddha-nature.Later, in the context of the convergence of three philosophies, scholars from other disciplines also began annotating the Diamond Sutra, fusing rich athāgata-garbha with Confucian and Taoist beliefs.)
