摩訶止觀 1.19

1.19

云何「圓建立眾生」？或放一光，能令眾生得即空即假即中益，得入出、雙入出、不入出益，歷行住坐臥語默作作亦如是。有緣者見，如目覩光；無緣不覺，盲瞽常闇。故舉龍王為譬，竪遍六天、橫亘四域，興種種雲、震種種雷、耀種種電、降種種雨，龍於本宮不動不搖，而於一切施設不同。菩薩亦如是，內自通達即空即假即中，不動法性而令獲種種益、得種種用，是名「圓力用建立眾生」。初心尚爾，況中、後心？如來殷勤稱歎此法，聞者歡喜。常啼東請，善財南求，藥王燒手，普明刎頭，一日三捨恒河沙身，尚不能報一句之力，況兩肩荷負百千萬劫，寧報佛法之恩？一經一說如此，餘經亦然。

What is meant by "perfectly establishing sentient beings"? It may be by emitting a single ray of light that enables sentient beings to attain the benefit of being identical to emptiness, identical to the provisional, and identical to the middle; to attain the benefit of entering, emerging, both entering and emerging, or neither entering nor emerging. It is likewise as they go through walking, standing, sitting, lying down, speaking, remaining silent, or undertaking various actions. Those with karmic affinity see it, as the eye beholds light; those without karmic affinity do not perceive it, being like the blind who remain perpetually in darkness. Hence, the dragon king is invoked as a simile: extending vertically throughout the six desire heavens and horizontally across the four continents, he raises diverse clouds, rolls diverse thunder, flashes diverse lightning, and pours down diverse rain; while the dragon in his original palace neither moves nor stirs, his manifestations are everywhere distinct. The bodhisattva is also like this: internally penetrating that which is identical to emptiness, identical to the provisional, and identical to the middle, without stirring from the dharmatā he causes [sentient beings] to obtain diverse benefits and acquire diverse functions. This is termed "establishing sentient beings through perfect power and function." If this is true of the initial mind, how much more so for the intermediate and final minds! The Tathāgata diligently praised this Dharma, and those who heard it rejoiced. Sadāprarudita journeyed east to seek it; Sudhana traveled south in search of it; Bhaiṣajyarāja burned his arms; Prabhāpāla cut off his head; [and even if one were to] abandon bodies as numerous as the sands of the Ganges three times a day, one could still not repay the power of a single verse, let alone by shouldering [the burden] for hundreds of thousands of myriads of kalpas—how could one ever repay the kindness of the Buddha-Dharma? What is said in one sutra is thus; the other sutras are likewise.
