（3）（名差别慧、色差别慧）在第三的二法中，欲修毗钵舍那（观）的人，依于四种非色蕴差别的慧为「名差别慧」。[PTS 43]

Ñ(XIV,11): 4. In the third dyad, when a man wants to begin insight, his understanding of the defining of the four immaterial aggregates is understanding as defining of mentality, [439]

Yā rūpakkhandhassa vavatthāpane paññā, ayaṃ rūpavavatthāpanapaññāti

依于色蕴的差别的慧为「色差别慧」。

Ñ: and his understanding of the defining of the material aggregate is understanding as defining of materiality.

evaṃ nāmarūpavavatthāpanavasena duvidhā.

如是依于名与色的差别的慧为二种。

Ñ: So it is of two kinds as the defining of mentality and of materiality.
