瑜伽論記 2.154

2.154

'Furthermore, those who seek an effect only grasp this cause and not others': for example, when seeking curd one grasps milk, and when seeking a pot one grasps clay, not grasping other causes; one should know that in the milk the nature of curd already exists beforehand, and in the clay the nature of the fruit of the pot already exists beforehand. This is the second reason.
