摩訶止觀 5.174

5.174

第四、明破法遍者，法性清淨，不合不散，言語道斷，心行處滅，非破非不破，何故言破？但眾生多顛倒，少不顛倒；破顛倒令不顛倒，故言「破法遍」耳。上善巧安心則定慧開發，不俟更破。若未相應，應用有定之慧而盡淨之，故言「破」耳。

Fourth, explaining the pervasive destruction of dharmas: dharmatā is pure, neither united nor scattered, the path of speech is cut off, the realm of mental activity is extinguished, neither destroyed nor not destroyed; why then speak of 'destroying'? It is only because sentient beings have many inversions and few non-inversions; to destroy inversions and make them non-inverted, we therefore speak of 'pervasive destruction of dharmas'. When the mind is skillfully settled as above, concentration and wisdom open and develop, and there is no need to destroy further. If one is not yet in accord, one should use wisdom possessed of concentration to cleanse it thoroughly; therefore we say 'destroy'.
