Therefore Hermeneutic theory is indispensible for Buddhism because many texts contain controversial stories. The main idea of Theravada Hermeneutics is to understand all conditioned things as impermanence, un-satisfactoriness and non-self. Particularly, non-attachment is regarded as the `gradual path` and `skillful means` to cultivate the conventional self and to realize the non-self. Traditionally, Buddhist hermeneutics accepts 2 levels of truth, the conventional and ultimate truths. By these concepts, Buddhist hermeneutics can accommodate both Schleiermacher`s theory of the author`s intention and Gadamer`s theory of fusion of horizon, because the former and the latter correspond to `gradual path` of Theravada and `skillful means` of Mahayana, respectivly. From the similar aspect, it can be said that Buddhism accepts both social self and social non-self. The former and the latter can be interpreted as `everyday ritual` and `beyond everyday ritual.` Self-identity in the light of right understanding through the self awareness or heedfulness must be cultivated to solve the problem of conflict occurring all over the world.
