摩訶止觀 6.102

6.102

二乘入空專依一門，無此弄引，教二弟子，謬授於藥。又少五意，何能入假？而菩薩善巧，大悲本願，大精進力，或寂諸想而發法眼，識知見病；或觀達見法，發道種智，明了惑法。若不悟者，但精進力勤研止觀，內因既熟，外被佛加，或冥或顯，豁然開悟，於諸見病，句句明了。如於鏡中見諸色像，自識識他，諦審無礙。

Practitioners of the two vehicles enter emptiness relying solely on a single portal, without this mastery; when teaching two disciples, they mistakenly prescribe medicines to them. Moreover, lacking these five considerations, how could they enter the provisional? But the bodhisattva, through skill-in-means, the original vow of great compassion, and the power of great vigor, either stills all thoughts and brings forth the Dharma-eye, discerning the sicknesses of views; or contemplates and penetrates the phenomena of views, giving rise to the knowledge of the paths and clearly understanding the phenomena of delusion. If one has not yet awakened, one need only use the power of vigor to diligently investigate calming and contemplation: once the internal cause matures and one is outwardly aided by the Buddhas, whether invisibly or visibly, one suddenly awakens, understanding every single proposition regarding the sicknesses of views clearly. Just like seeing forms and images in a mirror, one knows oneself and knows others, examining thoroughly without obstruction.
