無量壽經優婆提舍願生偈註 2.119

2.119

上國土莊嚴十七句、如來莊嚴八句、菩薩莊嚴四句為廣，入一法句為略。何故示現廣略相入？諸佛菩薩有二種法身：一者法性法身、二者方便法身。由法性法身生方便法身、由方便法身出法性法身，此二法身異而不可分、一而不可同，是故廣略相入統以法名。菩薩若不知廣略相入，則不能自利利他。

The seventeen lines on the land's adornments, the eight lines on the Tathāgata's adornments, and the four lines on the bodhisattvas' adornments above constitute the extensive; entering into the single Dharma phrase constitutes the brief. Why is the mutual entry of the extensive and the brief demonstrated? Buddhas and bodhisattvas have two kinds of Dharma body: the first is the Dharma-nature Dharma body; the second is the expedient Dharma body. The expedient Dharma body arises from the Dharma-nature Dharma body, and the Dharma-nature Dharma body issues forth from the expedient Dharma body. These two Dharma bodies are different yet indivisible, one yet cannot be made identical. Therefore, the mutual entry of the extensive and the brief is unified under the name of 'Dharma.' If a bodhisattva does not know the mutual entry of the extensive and the brief, he cannot achieve self-benefit and benefit others.
