俱舍論記 29.54

29.54

「十中前八至欲可見色」者，釋第二句。實緣色處，假想地等。故《正理》云「如何地等亦名色處？地、地界等有差別故。顯、形名地等，如先已說故。說地等遍處，不言地界等，故前八種但緣色處。風與風界既無差別，如何可言亦緣色處？此難非理，以諸世間亦說黑風、團風等故。由此前八緣色理成（已上論文）。」

"Among the ten, the first eight... visible matter of the desire [realm]": this explains the second line. In reality, they take the visible matter āyatana as object, while mentally imputing earth, etc. Therefore the Nyāyānusāra says: "How can earth and the rest also be called the visible matter āyatana? Because there is a distinction between earth and the earth element, etc. Visible color and shape are called earth, etc., as has been explained previously. When speaking of the totalities of earth, etc., it does not say the earth element, etc.; therefore the first eight take only the visible matter āyatana as object. Since wind and the wind element have no difference, how can it be said that it also takes the visible matter āyatana as object? This objection is unreasonable, because ordinary people also speak of black wind, whirling wind, etc. From this, the principle that the first eight cognize visible matter is established (above is the treatise text)."
