大方廣圓覺修多羅了義經略疏 2.402

2.402

能稱之行也。即如前二空觀門，根塵普淨，貪愛俱寂。悲智雙行，離相離心，常無所得，一切菩薩無不如斯。隨事雖差，此意無二故。

This is the practice that accords with it. That is, like the previous contemplation gates of the two emptinesses, sense faculties and dusts are universally purified, and greed and craving are completely quiescent. Compassion and wisdom are practiced together; free from marks and free from mind, constantly without anything attained—no bodhisattva fails to be like this. Although there are differences according to particulars, this intention is not twofold.
