十名一切諸佛道場者，三菩提道起於此經，故稱為場。〈神力品〉云「當知此處即是道場」，在處已然，經豈不爾？

"Tenth, it is called the Bodhimaṇḍa of All Buddhas": the path to saṃbodhi arises from this sūtra, hence it is called a "site" (maṇḍa). The "Chapter on Transcendent Powers" says, "You should know that this place is precisely the bodhimaṇḍa." If this is already true of the place, how could it not be so for the sūtra?
