It is widely acknowledged that the Consciousness-only System promoted by `Paramartha` a little contrasts with that promoted by Hsuan-Chiang. Hsuan-Chiang's teachings are taken as orthodox by Fa-Hsiang-Tzung，while Paramartha's interpretations are considered heterodox with the result that his original thoughts are gradually buried in oblivion. The following article will attempt to discuss, by means of recent scholarly researches, the original meaning of `Paramarthas` Doctrine of `Tri-svabhava` in Chuan-Shih-Lun. From this analysis a new explanation of Counciousness-only Thought can be found.
The article is divided into three sections. Firstly，the two different concepts, `vijnapti` and `vinana`，are presented in greater depth and analyzed. Both are translated into Chinese as consciousness, so it is necessary to define them more concisely. `Vijnana` in its simplest definition is "the knowing subject"，whereas `vijnapti` "the knowing subject which includes the known object". Secondly，it will be known through an analysis of `pratibhasa` that it means both the contradiction of the subject to the object and the identification of the subject with the object，and that `vijnapti` is similar to `pratibhasa` in some ways. Lastly，because it is said in Chuan-Shih-Lun that each of the eight consciousnesses contains the knowing and the known, and that the knowing is `paratantra-svabhava`，while the known is `parikalpita-svabhava`，we can find that this kind of relationship between the subject and the object is the core of `Paramarthas` Doctrine of Tri-svabhava.
