俱舍論疏 9.179

9.179

論「豈不地界至其體亦有」，有部難也。汝說地界不越髮、毛成了義說。洟涕等中豈無地界？寧不越彼？故知此經非為了義。

On the Śāstra's statement: 'Is not the earth element, up to: its entity also present?': the Sarvāstivādins object. You say that the earth element does not exceed hair and bodily hair and is a definitive teaching. Is the earth element not present in mucus and the like? How could it not exceed them? Therefore, we know that this sūtra is not definitive.
