妙法蓮華經玄義 6.104

6.104

和伽羅那者，說三乘、六趣、九道劫數，當得作佛。若後爾所歲，當得聲聞、支佛。後爾所歲，當受六趣報，皆名授記。夫授記法，面門放五色光，從上二牙出，照三惡道。下二牙出，照人天。光中演說，無常無我，安隱涅槃。遇光聞法者，三途中身心安樂，人中癃殘者差，六欲天厭患欲樂，色天厭禪樂。光照十方，遍作佛事，還遶七匝，從佛足下入，是記地獄道。[跳-兆+專]入、髀入、臍入、胸入、口入、肩間入、頂入者，是記佛道。《論》不見記脩羅光，當是開鬼道出脩羅，從容在於髀臍之間耳。

As for *vyākaraṇa*, stating the kalpas for the three vehicles, six destinies, and nine paths to attain buddhahood; or that after such-and-such years one will attain the state of a śrāvaka or pratyekabuddha; or that after such-and-such years one will receive retribution in the six destinies—all these are called prophecies. Now, in the manner of conferring prophecy, the Buddha's mouth emits five-coloured light: from the upper two canines it emerges to illuminate the three evil destinies, and from the lower two canines it emerges to illuminate humans and devas. Within the light he expounds impermanence, non-self, and tranquil nirvāṇa. Those who encounter the light and hear the Dharma find peace and joy of body and mind in the three paths; among humans, the crippled and infirm are cured; the devas of the six desire heavens feel revulsion toward sensory pleasures; the devas of the form realm feel revulsion toward the joy of dhyāna. The light illuminates the ten directions, performing the Buddha's work everywhere, returns, circles the Buddha seven times, and enters beneath his feet: this prophesies the hell realm. If it enters the shanks, the thighs, the navel, the chest, the mouth, between the shoulders, or the crown of the head, this prophesies the buddha-path. The *Treatise* (*Dazhidulun*) does not mention a light prophesying asuras; this must be because the asuras are subsumed under the ghost realm, casually situated between the thighs and the navel.
