摩訶止觀 8.28

8.28

Moreover, beginners studying the contemplation of the middle sever lust, but unable to obtain benefit, give rein to their minds and practice unsubdued matters. At first, doing it once, they gain a slight, shallow benefit. From then on, they practice it constantly without ceasing, yet obtain no further benefit, continuing the practice without reform. Using their former benefit, they convert others to practice it, and further cite sūtras as proof. The disciples who receive this conversion merely crave sense pleasures, with not the slightest benefit of the path. Crudely plunging into indulgence, it eventually became a custom, defiling and humiliating the precepts, and insulting and polluting the Three Jewels. The overthrow and eradication of the Buddha-dharma by the Zhou dynasty all came from this. This is abiding in non-subduing and abiding in subduing; what has it to do with neither abiding in subduing nor in non-subduing? This is called great obstruction; what has it to do with non-obstruction? This is increasing non-paths; what has it to do with the Buddha-path? Such subduing and non-subduing are both called unsubdued. Why is this? They are all ordinary feelings, not the practice of the worthy and noble.
