摩訶止觀 5.193

5.193

依《佛藏經》前四句亦吹亦唾；後兩句結前吹唾耳。此六句專論於唾也。又《楞伽》云：「我從得道夜至涅槃夜不說一字。」佛因二法作如此說，謂：緣自法及本住法。「自法」者，彼如來所得，我亦得之；無增無減，離言說、妄想、文字、二趣。釋曰：「緣自法」是證聖真諦實性也。「離言說、妄想」者，不可思議也。「離文字」者，離假名也。「離二趣」者，離說、所說，想、所想，名、所名也。「本住法」者，謂古先聖道，法界常住。如道趣城，道為人行，非行者作道；城由道至，非至者作城。經曰：「士夫見平坦道，即隨入城，受如意樂。我及先佛，法界常住，亦復如是。是故二夜不說一字。」

Relying on the Fo zang jing, the first four phrases are both blowing and spitting; the last two phrases merely conclude the previous blowing and spitting. These six phrases deal exclusively with spitting. Furthermore, the Laṅkā[vatāra Sūtra] says: "From the night I attained the path until the night of nirvāṇa, I did not speak a single word." The Buddha made this statement based on two dharmas: namely, conditioning the self-attained dharma and the originally abiding dharma. Regarding "self-attained dharma," what that Tathāgata attained, I also have attained; it neither increases nor decreases, free from words, conceptual discrimination, letters, and the two extremes. Explanation: "conditioning the self-attained dharma" is realizing the true noble reality and real nature. "Free from words and conceptual discrimination" means inconceivable. "Free from letters" means free from provisional designations. "Free from the two extremes" means free from speaker and what is spoken, conceiver and what is conceived, namer and what is named. Regarding the "originally abiding dharma," it refers to the ancient noble path, the常住 (eternally abiding) dharmadhātu. Just as a road leads to a city, the road is for people to walk upon, not made by the walker; the city is reached via the road, not made by the one who reaches it. The sūtra says: "A man sees a level road, follows it into the city, and experiences joy as he wishes. The eternally abiding dharmadhātu of myself and former Buddhas is also like this. For this reason, between the two nights, I did not speak a single word."
