大方廣圓覺修多羅了義經略疏 2.181

2.181

此下第四、略分修證之位也。既顯覺智之源，復究輪迴之本，已知圓覺凡聖無殊，但未辦隨順圓覺之心，從凡至聖如何差別，故次明之。言略分者，三賢統為一位，十地、等覺合之一門。修即修圓覺，證即證圓覺，圓覺無差，約修智以明位地。文四：初三之初。

From here down is the fourth: briefly differentiating the stages of practice and realization. Having revealed the source of enlightened wisdom and thoroughly investigated the root of saṃsāra, it is already known that in perfect enlightenment ordinary people and sages do not differ; however, with respect to the mind that accords with perfect enlightenment, how distinctions exist from ordinary person to sage has not yet been delineated, so it is clarified next. "Briefly differentiating" means: the three sagely stages (sanxian) are unified into one stage, and the ten grounds (bhūmis) and equal enlightenment are combined into one gate. Practicing is practicing perfect enlightenment, and realizing is realizing perfect enlightenment; perfect enlightenment is without differentiation, yet the stages and grounds are clarified in reference to cultivated wisdom. The text has four parts: the first of the first three.
