四明十義書 2.206

2.206

何者？豈非本以不待觀境之文，欲成事法之觀不依陰境。此文既是先出觀心一釋之意，及乎正明觀心中顯然須依陰境，是則不依陰境之義自然破壞也。

Why? Is it not that you originally intended to use the text 'not depending on the object of contemplation' to establish that the contemplation of phenomenal teachings does not rely on the object of the aggregates? Since this passage is first setting forth the intention of the single interpretation of contemplating the mind, and when it comes to directly clarifying contemplating the mind, it clearly must rely on the object of the aggregates, then your doctrine of not relying on the object of the aggregates is naturally demolished.
