大方廣佛華嚴經隨疏演義鈔 28.5

28.5

疏「佛於其中說普法」者，就此普法，自有四義：一境智合說，真俗雙照曰普、妙智照達名光。二單約境說，體周曰普、用徹為光。三唯約智說，準境可知。四約融攝說，若事若理皆無障礙，一塵一行猶如帝網曰普、圓明顯煥為光。餘如十玄。

Regarding the commentary's statement, "The Buddha within it expounds the universal Dharma": concerning this universal Dharma, it inherently has four meanings. First, expounding object and cognition together: illuminating both the real and conventional is called "universal"; wonderful wisdom illuminating and penetrating is named "light." Second, expounding solely in terms of the object: its essence being all-pervading is called "universal"; its function penetrating through is "light." Third, expounding solely in terms of cognition: this can be known by analogy with the object. Fourth, expounding in terms of fusion and subsumption: both phenomena and principle are without obstruction; a single dust mote and a single practice are like Indra's net, which is called "universal"; perfectly manifest and brilliantly shining is "light." The rest is as in the ten mysteries.
