摩訶止觀 9.137

9.137

又觀此禪因緣生法即空、即假、即中，十法界從禪而生，從禪而滅。何以故？若因禪出生三途、六道法，即是增長二十五有，生六法界，滅四法界。若因禪出生背捨等法，伏二十五有，亦是摧翳六法界也。若觀背捨等無常者，是用生滅拙度破二十五有，滅六法界，生一法界。若觀禪因緣生法即空者，是用不生巧度破二十五有，滅七法界，生一法界。若觀禪即假者，是用無量拙度破二十五有及客塵煩惱，滅八法界，生一法界。若觀禪因緣生法即中者，是用一實巧度破二十五有及無明惑，滅九法界，生一法界。成王三昧，遍攝一切三昧，根本、背捨悉入其中，如流歸海；變根本、背捨悉成摩訶衍。攝義如流入海，滅義如淡盡，生義如鹹成。禪波羅蜜變彼慈定成無緣慈悲；變彼念佛成大念佛海，十方諸佛悉現在前；變彼神通成於如來無謀善權。

Furthermore, one contemplates that this dhyāna, as a dharma arisen from causes and conditions, is identical to emptiness, identical to the provisional, and identical to the middle: the ten dharmadhātus are born from dhyāna and cease from dhyāna. Why is this? If through dhyāna one gives rise to the dharmas of the three wretched paths and the six destinies, this increases the twenty-five states of existence, giving rise to six dharmadhātus and extinguishing four dharmadhātus. If through dhyāna one gives rise to dharmas such as the liberations, subduing the twenty-five states of existence, this also crushes and conceals the six dharmadhātus. If one contemplates the liberations and so forth as impermanent, this uses the clumsy deliverance of arising and ceasing to break through the twenty-five states of existence, extinguishing six dharmadhātus and giving rise to one dharmadhātu. If one contemplates that the dharmas arisen from causes and conditions in dhyāna are identical to emptiness, this uses the skillful deliverance of non-arising to break through the twenty-five states of existence, extinguishing seven dharmadhātus and giving rise to one dharmadhātu. If one contemplates dhyāna as identical to the provisional, this uses the clumsy deliverance of the immeasurable to break through the twenty-five states of existence and adventitious defilements, extinguishing eight dharmadhātus and giving rise to one dharmadhātu. If one contemplates that the dharmas arisen from causes and conditions in dhyāna are identical to the middle, this uses the skillful deliverance of the single reality to break through the twenty-five states of existence and the delusion of avidyā, extinguishing nine dharmadhātus and giving rise to one dharmadhātu. This accomplishes the king samādhi, which universally gathers all samādhis; the fundamental dhyānas and the liberations all enter into it, like rivers flowing into the sea; transforming the fundamental dhyānas and liberations, they all become the Mahāyāna. The meaning of gathering is like rivers entering the sea; the meaning of extinguishing is like fresh water being spent; the meaning of arising is like saltiness being accomplished. Dhyāna-pāramitā transforms that concentration of loving-kindness into objectless loving-kindness and compassion; transforms that buddha-mindfulness into the great ocean of buddha-mindfulness, where all the Buddhas of the ten directions appear before one; transforms those supernormal powers into the Tathāgata's uncalculated skillful means.
