摩訶止觀 4.166

4.166

利使五蓋障於真諦，如前所明空見之人，計所執為實，餘是妄語。乖之則瞋，順之則愛，即貪、瞋兩蓋也；無明闇心，謬有所執，非明審知，即睡眠蓋；種種戲論，見諍無益，即掉悔蓋；即雖無疑，後方大疑。何以故？既執是實，何所復疑？後若被破，心生疑惑。此五覆心終不見諦。

The five hindrances of sharp proclivities obstruct the true truth. As explained previously regarding those with views of emptiness, they grasp what they adhere to as real and [regard] the rest as false speech. When things oppose it, there is hatred; when things accord with it, there is attachment—these are the two hindrances of greed and hatred. The dark mind of avidyā erroneously holds to attachments without clear and discerning knowledge; this is the hindrance of drowsiness and sleep. Various types of conceptual proliferation and disputes over views without benefit; this is the hindrance of restlessness and regret. While at that moment there is no doubt, later there arises great doubt. Why? Since they grasp it as real, what is there left to doubt? Later, if it is refuted, doubt arises in their mind. These five cover the mind so that one never sees the truths.
