「威儀、工巧處」者，有三解。一云：威儀謂表色，路體則四塵，四塵是彼所依，故說威儀路。但言威儀，不言路者，非四塵故。二云：威儀，四塵為性，路即發彼心，與彼為依，說心為路。工巧處亦爾，但是五塵、四塵別故。三云：威儀多於道路施設，工巧多於處所施設，故各別名，其實相似。七分別以尋伺或五、七、八識為體，任運分別是五、七、八識故，七唯有漏，有通無漏。《唯識》第七解。

Regarding "postures and bases of technical skills," there are three explanations. The first says: Posture refers to unmanifest and manifest form; the "path" in its essence comprises the four sense data, and since the four sense data are its support, it is called the "path of postures." When it merely says "postures" without saying "path," it is because it is not the four sense data. The second says: Posture has the four sense data as its nature; the "path" is the mind that initiates them, which serves as their support, so the mind is called the "path." The bases of technical skills are also like this, differing only in being five sense data versus four sense data. The third says: Postures are mostly established in relation to roads and paths, while technical skills are mostly established in relation to places, hence they have distinct names, but in reality they are similar. The seven kinds of discrimination have vitarka and vicāra, or the fifth, seventh, and eighth consciousnesses as their essence; since spontaneous discrimination is the fifth, seventh, and eighth consciousnesses, [some of the] seven are exclusively defiled, while some extend to undefiled, as explained in the seventh fascicle of the Vijñaptimātratāsiddhi.
