大方廣佛華嚴經隨疏演義鈔 18.59

18.59

疏「無分別言顯無差別」者，即此第二意。然所觀二境無分別故，能觀之智亦無分別，故無分別言顯無差別。此顯平等性智無分別義，與鏡智不同，鏡智無分別，若明鏡之無心；平等性智無分別，如日合空，空無異相，名無差別，謂不分別差別相故。故《攝論》第八云「應知一切法，本性無分別。所分別無故，能分別亦無。」

Regarding the commentary's "The phrase 'without conceptual differentiation' reveals being without distinction": this is the second meaning. Since the two contemplated realms are without conceptual differentiation, the contemplating cognition is also without conceptual differentiation; hence the words "without conceptual differentiation" reveal being without distinction. This reveals that the meaning of non-differentiation in the equality nature cognition differs from that in the mirror cognition: the non-differentiation of mirror cognition is like a bright mirror being without intention; the non-differentiation of equality nature cognition is like the sun uniting with empty space, where empty space has no disparate characteristics, which is termed "without distinction," meaning that it does not conceptualize differentiated characteristics. Therefore, the eighth fascicle of the *Mahāyānasaṃgraha* says: "One should know that all phenomena / Are by original nature free from conceptual differentiation. / Since what is differentiated does not exist, / That which differentiates also does not exist."
