首楞嚴義疏注經 1.587

1.587

先光，次見，後拳也。不從問次者，文便故也。閻浮檀金，正云染部捺陀，此西域河名，其河近其樹，其金出彼河，此則河因樹名，金因河稱也。或云閻浮果汁，點物成金，因流入河，染石為金也，其色赤黃，兼帶紫焰故也。《觀經疏》說：閻浮檀金，超過紫磨金色百千萬倍，唯聖所知。佛身光明猶如聚日，紫磨必不如此。赩，許力反，大赤色也。

First the light, next the seeing, and last the fist. It does not follow the order of the question because this is convenient for the text. Jāmbūnada gold is properly called *jambū-nada*; this is the name of a river in the Western Regions. The river is near that tree, and the gold comes from that river; thus the river is named after the tree, and the gold is named after the river. Alternatively, it is said that the juice of the jambū fruit turns objects into gold upon contact; flowing into the river, it dyes the stones into gold. Its color is reddish-yellow, tinged with a purple flame. The *Guanjing shu* states: 'Jāmbūnada gold surpasses purple-refined gold hundreds of thousands of times; only the sages know it.' The radiance of the Buddha's body is like an accumulation of suns, whereas purple-refined gold is certainly not like this. *Xi* (赩) is pronounced with the fanqie *xu-li*; it means an intense red color.
