維摩經玄疏 2.112

2.112

第五、成諸乘義者，三觀即是三智。三智有二種：一，別相三智；二，一心三智。一，別相三智，即開三乘；二，一心三智，但是一佛乘也。

Fifth, accomplishing the meaning of the various vehicles: the three contemplations are precisely the three wisdoms. There are two kinds of the three wisdoms: first, the distinct-aspect three wisdoms; second, the three wisdoms in a single mind. First, the distinct-aspect three wisdoms unfold the three vehicles; second, the three wisdoms in a single mind are only the one Buddha vehicle.
