摩訶止觀 7.199

7.199

學禪者亦如是。但專一法，治惑即去，當時微益，終非大途包括之意，亦不能破煩惱入無生忍。雖善醫藥，不依方服，病豈差乎？讀誦止觀甚利，心不行用，無生終不現前。

Those who learn dhyāna are also like this. If one merely focuses on a single method, curing the delusion removes it, bringing slight benefit at that moment; but in the end it is not the meaning of encompassing the great path, nor can it destroy afflictions to enter the patience of non-arising. Although skilled in medicine and herbs, if one does not take them according to the prescription, how could the illness be cured? Chanting and reciting Calming and Contemplation is very sharp, but if the mind does not put it into practice, non-arising will never manifest.
