The svabhāva(self-nature) has positive and negative both meanings in Buddhist philosophy. However the interpretation of svabhāva taken a positive or negative meaning has become one of the fundamental problems of Buddhist texts. Which the svabhāva in Mahāprajñāpāramitā Sūtra and Mūlamadhyamaka-kārikā all were taken negative meaning. But after then, the svabhāva was transferred to positive meaning, even was equal to buddha-nature in the Tathāgatagarbha texts. Hereafter, except the Tathāgatagarbha texts, svabhāva also has been explained positive meaning in other texts. For example, the Mūlamadhyamaka-vṛtti-prasannapadā, which was worte Candrakīrti(A.D.600-650) discripted that the nature of things(dharma)、nature(prakṛti)、emptiness(śūnyatā)、self(svabhāva)、and non-self-nature(nihsvabhāva) all are synonyms actually. Until now, we don't know when the meaning of self-nature has been changed. But on this article, I will indicate Lankāvatāra-sūtra(about 4-5 centuries, the rest omitted as LAS) has actually appeared both positive and negative meanings on self-nature. Anyway, that is exactly the unique style of LAS, which the two concepts of contradiction will be to one, and named as the pratyātmagati-(means subjective wisdom), or pratyātmagatigocara(means objective things).
