形亦非實有者，是經部宗標破有宗實有形色。故論云：「然經部師形非實有，謂顯色聚一面多生，假立長色。待此長色，於餘色聚一面少中假立短色，於四方面並多生中假立方色，於一切處遍滿生中假立圓色。所餘形色如應當知（所餘形色，謂高、下等，皆假立也）。如見火㷮於一方面無間速運，便謂為長。見彼周旋，謂為圓色。故形無實別類色體。」

'Shape is also not substantially existent': the Sautrāntika school marks its refutation of the Sarvāstivāda view that physical shape is substantially existent. Therefore the treatise says: 'However, according to the Sautrāntika masters, shape is not substantially existent; that is to say, when a collection of color-matter arises predominantly on one side, long shape is designated nominally. In relation to this long shape, where another collection of color-matter arises sparsely on one side, short shape is designated nominally; where it arises extensively on all four sides, square shape is designated nominally; where it arises completely filling all places, circular shape is designated nominally. The remaining shapes should be understood accordingly (the remaining shapes refer to high, low, etc., which are all nominally designated). Just as seeing a firebrand moved swiftly and continuously in one direction leads one to call it long, and seeing it whirled around leads one to call it a circular shape, so shape has no distinct, substantial category of physical entity.'
