維摩經玄疏 6.36

6.36

First, as for the two truths external to principle: they do not clarify the two truths in terms of buddha-nature, which is like still staying outside the gate, stopping to lodge in a thatched hut. Now, clarifying these two truths external to principle, there are three kinds: first, the two truths conforming to sentiment; second, the two truths of sentiment and wisdom; third, the two truths conforming to wisdom.
