This paper takes up the relation and negotiation between Zhanran's “tathagatagarbha-move along” thought and Fazang's Qixinlun yiji . The Tientai School was built on “The true form of all things as they are,” but it began to approach Huayen tathagatagarbha thought from the middle of the Tang dynasty. I tried to prove that the Tientai School's central theory was based on “The union of two phenomena,” rather than tathagatagarbha thought by comparing the Zhanran's “tathagatagarbha-move along” thought with Fazang's tathagatagarbha thought in his Qixinlun yiji . The most important part in Zhanran's thought is that it always follows the principle that “Worldly desires are not different from Bodhi, life-and-death or transmigration is also not different from nirvana.” Zhanran's thought is different from Fazang's “tathagatagarbha-move along” thought that has a dynamic meaning for the arising of all phenomena accordingly. My conclusion is that Zhanran's “tathagatagarbha-move along” thought is not really “move along” because it didn't act according to the reality of dependent origination.
