佛以一音演說法。眾生隨類各得解。皆謂世尊同其語。斯則神力不共法　此下六行歎口密四辯。此初二行法詞二辯也。隨類各解諸法名字不同。此法辯也。皆謂世尊同其言音此詞辯也。佛得一切眾生語。言陀羅尼。無言之言不與二乘共也。

"The Buddha expounds the Dharma with a single voice, / And sentient beings each attain understanding according to their kind, / All thinking the World-Honoured One speaks in their own tongue: / This is the unshared dharma of his spiritual power." The six lines below praise the four unimpeded eloquence-skills of the mystery of speech. The first two lines here are the two unimpeded eloquence-skills in phenomena and words. That they each understand according to their kind the different names of all phenomena is unimpeded eloquence in phenomena. That all think the World-Honoured One speaks in their own language and voice is unimpeded eloquence in words. The Buddha has attained the dhāraṇī of all sentient beings' speech; wordless speech is not shared with the two vehicles.
