玉豪（胡高反假借字也正體從毛作毫言玉毫者如來眉間白毫毛也晧白光潤猶如白玉佛從毫相放大光明照十方界故云玉毫瑞色也）。

玉豪 (h-[u]-g-[ao] fan; a borrowed character; the standard form derives from 毛 [hair], written as 毫 [háo]. Speaking of the 'jade hair', it is the white curl of hair (ūrṇā) between the Tathāgata's eyebrows. Brilliant white and lustrous, it is like white jade. From this hair-mark, the Buddha emits great light that illuminates the worlds of the ten directions; hence it is called 'the auspicious colour of the jade hair').
