摩訶止觀 4.149

4.149

貪欲蓋起，追念昔時所更五欲：念淨潔色與眼作對；憶可愛聲髣髴在耳；思悅意香開結使門；想於美味甘液流口；憶受諸觸毛竪戰動。貪如此等麁弊五欲，思想計校，心生醉惑，忘失正念；或密作方便，更望得之。若未曾得，亦復推尋，或當求覓，心入塵境，無有間念。麁覺蓋禪，禪何由獲？是名貪欲蓋相。

When the hindrance of sensual desire arises, one recalls past experiences of the five desires: recollecting pure and clean forms confronting the eyes; remembering pleasing sounds faintly echoing in the ears; thinking of delightful fragrances opening the gates of the defilements; imagining delicious flavors with sweet saliva watering the mouth; remembering tactile sensations that made the hairs stand on end and caused trembling. Greedily desiring such coarse and wretched five desires, one reflects and calculates, intoxication and delusion arise in the mind, and one forgets right mindfulness; or one secretly devises expedients, hoping to obtain them again. If one has never obtained them, one also searches them out or seeks after them; the mind enters the sensory realms without an interval of thought. Coarse sensations hinder dhyāna; how could dhyāna be attained? This is the characteristic of the hindrance of sensual desire.
