3.238

五中。儀云：𣰽毹純色入輕，雜者入重。（又云：叢毛編織而出毛頭，兼有文像人獸等狀，名曰𣰽毹。此即雜者。）律下，釋疑。恐謂律聽壞色而著，不當入重；準知染壞理在輕收。

In the fifth: The Ceremonial Standard states: "Woollen rugs of a single solid colour are reckoned as light; variegated ones are reckoned as heavy." (It also states: "Woven from tufts of wool so that the tips protrude, and also bearing patterns or forms of humans, beasts, and the like, it is called a woollen rug. This refers to the variegated kind.") Below "the Vinaya", it resolves doubts: fearing it might be thought that because the Vinaya allows them to be worn after corrupting the colour, they should not be reckoned as heavy, it is known by parity of reasoning that after being dyed and corrupted, in principle they are classed as light.
