俱舍論疏 30.166

30.166

論「以身於我至即是我身」，外道通論主難也。我有二種：一實、二假。實是真我，身是假我。以身於我有防護恩故，假說為我。如言臣等即是我身，身等覺同名為我者，此是假我非實我也。

On the Śāstra's statement: "Because the body protects the self [...] 'is my body'": The non-Buddhist resolves the author of the treatise's objection. We have two kinds of self: first, the real; second, the conventional. The real is the true self; the body is the conventional self. Because the body has the kindness of protecting the self, it is conventionally designated as "self." Just as one says a minister or the like "is my own body," that the cognition of the body and so forth is likewise named "self" is because this is a conventional self, not the real self.
