2.44

「云何名觀額廣平正額廣平正相？二輪光明，光明輪郭，千輻轂輞，成摩尼珠，形如毘紐羯磨天畫。於畫中流出上妙金色之光，來入白毫，遶毫七匝，上入額上諸毛孔中，乃至髮際諸色相中，婉轉下垂至于耳輪，上散入髮，遶髮七匝。從枕骨出遶前蓮華相，團圓七匝七畫分明，畫有七色色生七華，華有一佛有七菩薩以為侍者，恭敬圍遶右旋而轉。如是額廣平正三相：髮際相、頭諸毛孔相、腦中相。腦中亦有十四光，現諸脈中，中外俱徹明顯可愛，踊出白光紅紫間錯，其色微細從枕骨出，亦遶前者三匝。一一畫間有一佛坐，有二菩薩以為侍者，益更明顯勝前數倍。

“What is called contemplating the broad, flat, and even forehead, the mark of the broad, flat, and even forehead? There are lights of two wheels; the rims of the lights’ wheels, with hubs and rims of a thousand spokes, form maṇi jewels, in shape like a painting by the Viśvakarman deva. From within the painting flows out sublime golden-colored light, which comes and enters the white hair-tuft, circles the tuft seven times, ascends and enters into the pores on the forehead, and extends to the hairline among the various colored marks, meandering down to the ear-rims, and scattering upward into the hair, circling the hair seven times. Emerging from the occipital bone, it circles the preceding lotus mark, making seven round turns with seven distinct lines. The lines have seven colors, each color producing seven flowers, and each flower has a Buddha with seven bodhisattvas as attendants, reverently surrounding him and revolving to the right. Thus are the three marks of the broad, flat, and even forehead: the hairline mark, the mark of the pores on the head, and the mark within the brain. Within the brain there are also fourteen rays of light appearing within the channels, transparent both inside and outside, distinct and lovely, gushing forth white light interspersed with reddish-purple, whose color is subtle, emerging from the occipital bone and also circling the preceding [mark] three times. Between each line sits a Buddha, with two bodhisattvas as attendants, even more distinct and many times surpassing the previous ones.”
