俱舍論疏 1.153

1.153

論「有餘師說至第二十一」，述異說也。此師意說：空一顯色非是明、闇，別立此色，故二十一。依《婆沙》正義，空一顯色即是空界色一分，空界色即是明、闇等色，無別體性。然明、闇等，即青等四色差別而立。故《識身足論》第十一云「空一顯色，如青、黃等者，以是青等差別立也。或似青等之差別色，非即青等。」故言「如」也。

The treatise says: "Other masters say... the twenty-first," stating a divergent view. This master's intention is: the single color of space (ākāśaika-varṇa) is neither brightness nor darkness, so this form is established separately, making twenty-one. According to the correct view of the Vibhāṣā, the single color of space is simply a part of the form of the space element (ākāśa-dhātu-rūpa); the form of the space element is simply brightness, darkness, and such colors, with no separate substantial entity. However, brightness, darkness, and so forth are established as differentiations of the four colors of blue and so forth. Therefore the eleventh fascicle of the Vijñānakāya states: "The single color of space is like blue, yellow, and so forth, because it is established from the differentiations of blue and so forth. Or it is a differentiated form resembling blue and so forth, not identical with blue and so forth"; therefore it says "like".
