摩訶止觀 4.168

4.168

復次，依空起蓋，障俗諦理。所以者何？沈空取證，以空為是。譬如貧人，得少便為足，更不願好者。保愛此空，即貪蓋；憎厭生死，捨而不觀，即瞋蓋；無為空寂，不肯照假，乃至不識五種之鹽，名睡蓋；空亂意眾生，非其境界，名掉悔蓋；假智不明，名疑蓋。此蓋不棄，道種智、俗諦三昧終不現前。此蓋若除，法眼明朗。

Furthermore, relying on emptiness, hindrances arise that obstruct the principle of the conventional truth. Why is this? One sinks into emptiness to attain realization, taking emptiness as right. This is like a poor man who is satisfied as soon as he gets a little, no longer desiring anything better. Cherishing and loving this emptiness is the hindrance of greed; detesting and loathing saṃsāra, abandoning it without contemplating it, is the hindrance of hatred; unconditioned empty quiescence, refusing to illuminate the provisional, to the extent of not recognizing the five kinds of salt, is called the hindrance of sleep; beings with empty, distracted minds are not one's sphere, which is called the hindrance of restlessness and regret; and lack of clarity regarding provisional knowledge is called the hindrance of doubt. If these hindrances are not discarded, the knowledge of the aspects of the path (mārgākārajñatā) and the samādhis of conventional truth will never manifest. If these hindrances are removed, the Dharma eye becomes bright and clear.
