俱舍論疏 12.168

12.168

論「如聲熟變等從異類定生」，此即論主引喻顯也。如絲、竹、土、草與聲異類，所變清、濁之聲決定，無不定也。如火、土與食、鐵俱是異類，火然能熟食變，鐵、土即不能，豈非決定？

The treatise says: "Just as sound, cooking transformation, and the like definitely arise from different classes." Here the Master of the Treatise adduces analogies to illustrate. Just as strings, bamboo, clay, and grass are of different classes from sound, yet the clear and turbid sounds transformed by them are determined and not indeterminate; and just as fire and earth are of different classes from food and iron, yet fire can cook and transform food whereas iron and earth cannot—is this not determined?
