摩訶止觀 8.4

8.4

何者？生來雖瞋，諫曉則息；今所發者，咆勃可畏。生來倒想，乍起乍滅；今所發者，欝然不去。生來欲色，抑制可停；今所發者，不簡死馬，況其匹類？此惑內發，強梁熾盛；若見外境，心狂眼闇。譬如流水，不覺其急；概之以木，漣漪𭱯起。亦如健人，不知有力，觸之怒壯。煩惱臥伏，如有如無；道場懺悔，觀陰界入，如觸睡師子哮吼震地。若不識者，則能牽人作大重罪。非唯止觀不成，更增長惡業，墜黑闇坑，無能勉出。為是義故，須觀煩惱境也。

Why is this? Even if anger arose from birth, when remonstrated and reasoned with, it subsided; but what is aroused now is roaring, violent, and terrifying. Inverted thoughts from birth arose and ceased abruptly; what is aroused now is thick, stagnant, and will not depart. Lust for form from birth could be stopped by suppression; what is aroused now does not even discriminate against a dead horse, let alone its own kind! When this delusion surges from within, it is domineering and blazing; if it meets external objects, the mind goes mad and the eyes go dark. It is like flowing water whose swiftness is not noticed, but when checked by a piece of wood, surging ripples suddenly arise. It is also like a strong man who does not know his own strength, but when provoked, his rage is mighty. When the defilements lie dormant, they seem as if present yet absent; but when repenting in the bodhimaṇḍa and contemplating the aggregates, realms, and entrances, it is like prodding a sleeping lion whose roar shakes the earth. If one does not recognise them, they can drag one into committing grave offences. Not only will calming and contemplation fail to be accomplished, but bad karma will further increase, plunging one into a dark pit with no way to escape. For this reason, one must contemplate the realm of defilement.
