下明廢立，略有七重。初約百法以明廢立。何故色法及不相應法不立禪支？答隨順義是禪支義也，不隨順故不立支。又相應緣境有勢用義則立禪支，不相應法不爾故不立支。

Below, the rejection and establishment are explained, having roughly seven tiers. First, explaining the rejection and establishment in terms of the hundred dharmas: Why are material dharmas and non-conjoined formations (citta-viprayukta-saṃskāra) not established as dhyāna limbs? Answer: The meaning of being compliant/conducive is the meaning of a dhyāna limb; because they are not compliant, they are not established as limbs. Furthermore, when there is conjunction, taking an object, and having efficacy, then it is established as a dhyāna limb; non-conjoined dharmas are not like this, and therefore are not established as limbs.
