法華論疏 3.272

3.272

初標法佛菩提，法即是性淨涅槃真如法。即如體有覺義，故名為佛。至妙虛通名之為道，道即菩提也。謂如來藏性淨涅槃者，出法佛菩提體，經論不同。餘經云「隱名如來藏、顯名法身。」此論正以如來藏為法身，顯即名報身。言性淨涅槃者，涅槃有二種：一性淨、二方便淨。本性清淨名為性淨，修方便斷煩惱得淨名方便淨。今此用性淨涅槃是法佛菩提，方便淨屬報佛也。二淨即是《攝論》有垢真如、無垢真如也。常恒清涼不變者，出性淨涅槃體。此性淨涅槃，體是常住，故言常恒。《攝論》云「清者是淨，涼者是樂。」是淨樂二德，故言清涼也。又云「清者有餘，涼者無餘。」宜用前意釋此文。不變如上釋。

First, the heading presents the bodhi of the Dharma Buddha. "Dharma" is precisely the dharma of thusness of the naturally pure nirvāṇa. The very substance of thusness has the meaning of awakening; hence it is called "Buddha." What is supremely subtle, empty, and pervasive is termed the "Path" (mārga), and the Path is bodhi. "The naturally pure nirvāṇa of the tathāgatagarbha" sets forth the essence of the bodhi of the Dharma Buddha; sūtras and treatises differ on this. Other sūtras say: "When concealed, it is called the tathāgatagarbha; when revealed, it is called the dharmakāya." This treatise specifically takes the tathāgatagarbha to be the dharmakāya, and when revealed, it is called the retribution body. Regarding "naturally pure nirvāṇa," there are two kinds of nirvāṇa: first, naturally pure; second, pure through skillful means. Original purity of nature is called naturally pure; cultivating skillful means to sever afflictions and attain purity is called pure through skillful means. Here, naturally pure nirvāṇa is the bodhi of the Dharma Buddha, while purity through skillful means belongs to the retribution Buddha. These two purities are precisely the defiled thusness and undefiled thusness of the Mahāyānasaṃgraha. "Permanent, cool, and unchanging" sets forth the essence of naturally pure nirvāṇa. The substance of this naturally pure nirvāṇa is permanently abiding; therefore it is said to be "permanent." The Mahāyānasaṃgraha states: "'Purity' is clean; 'coolness' is bliss." These are the two virtues of purity and bliss, hence it says "cool." It also says: "'Purity' is with remainder; 'coolness' is without remainder." It is appropriate to use the former meaning to explain this text. "Unchanging" is explained as above.
