維摩經玄疏 3.75

3.75

三、別教別詮三諦理，所以稟教之流，三十心但成二觀、二智方便，登地方乃見佛性、入法流也。

Third, the distinctive teaching distinctively expresses the principle of the three truths; therefore, for those who receive this teaching, the thirty minds merely accomplish the expedients of the two contemplations and two wisdoms, and only upon ascending the grounds do they see buddha-nature and enter the flow of Dharma.
