【第十九折】
Scene 19
今既如是，此法門中，何名坐禪？此法門中，一切無礙，外於一切境界上念不起為坐，見本性不亂為禪。何名為禪定？外離相曰禪，內不亂曰定。外若離相，內性不亂。本性自淨曰定，只緣境觸，觸即亂，離相不亂即定。外離相即禪，內不亂即定，外禪內定，故名禪定。《維摩經》云：「即時豁然，還得本心。」《梵網菩薩戒經》云：「本源自性清淨。」善知識！見自性自淨，自修自作自性法身，自行佛行，自作自成佛道。
Now, in this teaching, what does "sitting in meditation" mean? In this teaching, nothing is hindered. Not giving rise to thoughts while facing all external conditions is called "sitting"; seeing your own nature without confusion is called "meditation." What is "meditation concentration" (Chan Ding)? Detaching from external appearances is called Chan (meditation), and inner calmness without confusion is called Ding (concentration). If you can detach from appearances externally, your inner nature will remain calm. Your fundamental nature is originally pure, and that purity is concentration—but if you encounter conditions and become disturbed, you lose it. When you detach from appearances and stay undisturbed, that is concentration. Detaching from outer appearances is Chan, and inner calmness is Ding. When outer Chan and inner Ding are united, it is called "Chan Ding." The Vimalakirti Sutra says: "In an instant, there is a clear awakening, and you regain your original mind." The Brahma Net Sutra says: "The original source is naturally pure." Good friends! See your true nature's inherent purity; cultivate and act on your own, realizing your nature's Dharma body, practicing the Buddha's way yourself, and accomplishing the Buddha path on your own.
