六妙法門 1.25

1.25

復次，行者於其中間，若有內外障起，欲除却者，亦當於六門中隨取一法，一一試用却之。若得差者，即為藥也。治禪障及禪中魔事、病患，功用六門悉得差也。上來所說，其意難見。行者若用此法門，當善思惟取意，勿妄行也。

Furthermore, if in the interim internal or external obstacles arise for the practitioner and one wishes to eliminate them, one should also take up any one method from among the six gates and test them one by one to eliminate [the obstacle]. If one is cured, that is the medicine. For treating obstacles to dhyāna as well as demonic affairs and illnesses during dhyāna, using the six gates will cure them all. The meaning of what has been explained above is difficult to perceive. If a practitioner uses this dharma gate, one must reflect skillfully to grasp its intention, and not practice recklessly.
