瑜伽論記 19.7

19.7

Regarding the statements "being unable to conceal what has already been revealed" and "being able to conceal what has already been revealed": here there are two explanations. The first explanation says: external light cannot conceal phenomena that have already been revealed; just as with an object already illuminated and revealed by fire, although sunlight is superior, it cannot conceal it such that the illuminated object fails to appear. The light of wisdom is not like this: higher wisdom conceals the phenomena already revealed by lower wisdom, so that they become obscure and do not arise. The second explanation says: phenomena that have already been revealed as known by conventional wisdom, when viewed by real wisdom, have their lower conventional marks concealed; this is called "concealing what has already been revealed." External light is not like this.
