妙法蓮華經玄贊 2.111

2.111

贊曰：下第五依止說因成就。論有二釋：一云彼諸大眾現見異相不可思議事，如來應為我說，渴仰欲聞生希有心，名依止說因成就，是故放大光明示現諸世界中種種事故。夫佛說法必為濟生，生發希渴之心名為說因，此將說法所依止因，因生希渴而為說故，放光遠照異相難知，大眾覩光遂興正念，佛將為說渴仰冀聞，既生希有之心次應當為說法，是故放光能生眾生渴仰心，故名為說因。二云先示現外事六種震動等，後示現此法門內證深密法故，所以先現神通外事，表佛說此法門乃是由內證深密法；又由內證深密，所以外現神變，神變既彰表佛將說所證之法，故名說因。雖先雨華動地，未是殊絕之能，今放神光希奇更甚，由內證深密故外現難思。由此說因，獨標斯瑞，此中有三：一放光、二照境、三所見，此初也。「眉」者面首之媚，表所說勝大乘完媚。「間」謂兩中，表說中道。「白」為眾色之本，顯此法是三乘之源，所以喻白蓮華、白牛馳駕也。「豪」者長毛，亦有為豪毛也。《觀佛三昧海經》第一云：「太子時舒長五尺，樹下長一丈四尺五寸，成佛已長丈五尺，有十楞現，中外俱空旋之圓卷如秋滿月，分明晈色映雪珂，圍如三寸。」光有七義：一令生淨信知是勝人；二破暗瞑癡愚併蕩；三能導明引出世故；四表內發智光；五濟眾苦，由放光照眾苦息除；六警群情，由覩光明有緣皆至；七令厭色境，諸眾生等貪生死之境久沈生死，覩佛光明遂厭生死之色故佛放光。《涅槃》從面門而放四光，《上生》舉佛身而縱金色，今從眉間放其白光，各有表矣。神境智通有十八變：一振動、二熾燃、三流布、四示現、五轉變、六往來、七卷、八舒、九眾像入身、十同類往趣、十一隱、十二顯、十三所作自在、十四制他神通、十五能施辨才、十六能施憶念、十七能施安樂、十八放大光明。雨四華者自在之變，振六種者振動之變，此放光者流布之變，見六道等示現之變，下〈神力品〉當具顯示。

Eulogy: Below is the fifth [section], the fulfillment of the cause for preaching based upon which [the Dharma is taught]. The treatise gives two explanations: The first says that when the great assembly sees before them unusual marks and inconceivable events, [they think,] "The Tathāgata ought to preach for me," and longing with thirst and desiring to hear, they give rise to a rare mind; this is called the fulfillment of the cause for preaching based upon which [the Dharma is taught]. Therefore, he emits great light to display various matters in all world-systems. Whenever a buddha preaches the Dharma, it must be to save sentient beings; when sentient beings give rise to a mind of rare longing, that is called the cause for preaching. This is the underlying cause for the impending preaching of the Dharma, for it is because of the thirst of sentient beings that he preaches. When he emits light shining afar, the unusual marks are difficult to fathom; when the great assembly beholds the light, they give rise to right mindfulness, and as the Buddha is about to preach for them, they long with thirst hoping to hear. Once they have given rise to a rare mind, next he ought to preach the Dharma for them; therefore, emitting light can give rise to the longing mind of sentient beings, and hence it is called the cause for preaching. The second says that first he displays external matters such as the six kinds of shaking, and later he displays this Dharma-door of the profound and secret Dharma realized internally. Therefore, he first displays the external matters of spiritual superknowledges to show that the Buddha's preaching of this Dharma-door is precisely due to the profound and secret Dharma realized internally. Furthermore, because he has realized the profound and secret internally, he manifests spiritual transformations externally. Once the spiritual transformations are made manifest, they show that the Buddha is about to preach the Dharma he has realized; hence it is called the cause for preaching. Although the raining of flowers and the shaking of the earth happened first, they were not yet peerless abilities; now the emission of spiritual light is even more extraordinary and rare: because he has realized the profound and secret internally, he manifests the unfathomable externally. Due to this cause for preaching, this auspicious sign is exclusively singled out. Within this there are three parts: first, emitting light; second, illuminating the realms; third, what is seen. This is the first. "Eyebrows" are the charm of the face and head, representing that what is preached is the supreme Great Vehicle, which is complete and charming. "Between" means between the two, representing the preaching of the Middle Way. "White" is the root of all colors, revealing that this Dharma is the source of the three vehicles, which is why it is compared to the white lotus flower and the driving of the white ox cart. "Curl" (hao) is a long hair; it is also written as a fine hair. The first fascicle of the Guanfo sanmei hai jing says: "When he was crown prince, when stretched out it was five feet long; under the tree, it was fourteen feet and five inches long; after attaining buddhahood, it was fifteen feet long. Ten ridges appear; it is empty both inside and outside, and coiled circularly like the autumn full moon, with a clear, gleaming color mirroring snow and white jade, three inches in circumference." The light has seven meanings: first, to cause pure faith to arise, knowing that he is a superior person; second, to destroy darkness, utterly sweeping away delusion and ignorance; third, to be able to guide with illumination, leading beings out of the world; fourth, to represent the inner emission of the light of wisdom; fifth, to rescue from all sufferings, for because the emitted light shines, all sufferings cease and are eliminated; sixth, to alert the minds of the multitude, so that by beholding the light all those with affinity arrive; seventh, to cause revulsion toward physical objects: all sentient beings, coveting the objects of birth and death, have long sunk in birth and death, and upon beholding the Buddha's light, they come to loathe the forms of birth and death; hence the Buddha emits light. In the Nirvāṇa [Sūtra] he emits four lights from his mouth; in the Shangsheng [jing] he raises the Buddha's body and casts a golden color; now he emits this white light from between his eyebrows, each having its own symbolic meaning. The superknowledge of psychic power (ṛddhividhijñāna) has eighteen transformations: first, shaking; second, blazing; third, pervading; fourth, displaying; fifth, changing; sixth, going and coming; seventh, contracting; eighth, expanding; ninth, entering the body with myriad forms; tenth, going to similar types; eleventh, disappearing; twelfth, appearing; thirteenth, mastery of actions; fourteenth, controlling others' superknowledges; fifteenth, being able to bestow eloquence; sixteenth, being able to bestow mindfulness; seventeenth, being able to bestow ease and bliss; eighteenth, emitting great light. Raining the four flowers is the transformation of mastery; shaking the six kinds is the transformation of shaking; this emission of light is the transformation of pervading; seeing the six destinies and so forth is the transformation of displaying; they will be fully shown below in the Supernatural Powers Chapter.
