因明入正理論疏 3.212

3.212

述曰：此釋所由。由彼諸智於四塵境，不以自相為所觀境，於上增益別實有物而為所緣，名曰異轉。此意以瓶、衣等體即四塵，依四塵上唯有共相，無其自體。此知假名瓶、衣，不以本自相四塵為所緣，但於此共相瓶、衣假法而轉，謂為實有，故名分別。

The commentary says: This explains the cause. Because those cognitions, with respect to the objects of the four sense-spheres, do not take their own-characteristic as the observed object, but superimpose an extraneous real entity upon them as that which is apprehended, this is called "operating aberrantly". The meaning here is that the substance of pots, cloth, and the like is merely the four sense-spheres; upon the four sense-spheres there is only a common characteristic (sāmānyalakṣaṇa), with no individual substance of its own. This cognition of the nominal pots and cloth does not take the four sense-spheres in their fundamental own-characteristic as its cognitive object, but merely operates upon these conceptual designations of pots and cloth possessing a common characteristic, regarding them as real existents; therefore it is called conceptual construction.
