俱舍論疏 13.63

13.63

論「豈不現見至而形相異者」，有部救。如世瓦器，黃、白雖同，而有瓶、瓫相各異故，故知顯外別有形微。

On the Śāstra's statement: "Is it not visibly observed [... to ...] yet their shapes and marks differ?": This is the Sarvāstivādin's rescue. Just as in worldly earthenware, although the yellow and white [colors] may be the same, the marks of jars and basins differ from each other; therefore we know that apart from visible color there are distinct shape-atoms.
