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.
