俱舍論疏 9.245

9.245

論「我語謂內身依之說我故」，釋我語取。即此內身實非我語，依之起我語故名我語，此是有財釋也。

The treatise says: "'Doctrines of self' refers to the internal body, because based on it one speaks of a self." This explains grasping at doctrines of self. Namely, this internal body is not in reality the doctrine of a self, but because based upon it one gives rise to the doctrine of a self, it is named "doctrines of self." This is a possessive compound (bahuvrīhi).
