下次明其智人能解。「智臣善知」總明能解，「若王洗」下別明能解，「如是」下結。合中，先合王之密語，「大乘如是」合先陀婆。準合求之，彼先陀婆所況之法有總、有別，總喻大乘，別喻如來、法、僧、解脫及與佛性，理實通喻一切密語，且論斯耳，良以所況有斯總別，故今合中總以大乘合先陀婆。

Next, it clarifies that wise persons are able to understand. "The wise minister knows well" generally clarifies the ability to understand; from "If the king washes..." downward separately clarifies the ability to understand; from "Such as..." downward concludes. In the matching, first it matches the king's secret words: "The Mahāyāna is like this" matches saindhava. Investigating in accord with the matching, the dharma illustrated by that saindhava has both a general and particular sense: generally it illustrates the Mahāyāna, and particularly it illustrates the Tathāgata, the Dharma, the Saṅgha, liberation, and buddha-nature. In principle it actually illustrates all secret words generally; here it is just discussed in this way for now. Truly because what is illustrated has these general and particular aspects, now in the matching it takes the Mahāyāna as a whole to match saindhava.
