述曰：若准前第三解，此答第一問。所知障不發業等故，二乘入涅槃、解脫者，謂二涅槃，解除縛義，故名解脫，煩惱名縛，能障涅槃，所知障非縛，不障涅槃，涅槃解脫故。既不障解脫，體非縛法，無如無明等，能發有漏業及如貪等，潤生用故，此所知障若能發業潤生，縛有情故，可別障解脫，此既不爾，故不障解脫。

The Commentary states: Following the third explanation above, this answers the first question. Because the cognitive hindrance does not initiate karma and so forth, the two vehicles enter nirvāṇa and liberation—that is, the two nirvāṇas. Liberation means resolving the bonds, hence it is called liberation. Defilements are called bonds and can obstruct nirvāṇa; the cognitive hindrance is not a bond and does not obstruct nirvāṇa, for nirvāṇa is liberation. Since it does not obstruct liberation and its essence is not a binding dharma, it lacks the function of initiating defiled karma like ignorance, or of moistening rebirth like craving and the like. If this cognitive hindrance could initiate karma and moisten rebirth, binding sentient beings, it would distinctly obstruct liberation; but since this is not the case, it does not obstruct liberation.
