若在護世中尊護諸眾生　護世四天王也。東方持國主。主二部揵闥婆毘舍闍。南方增長主。主二部鳩槃荼薜荔多。西方雜語主。主二部龍及富單那。北方多聞主。主二部夜叉羅剎。護諸世間也。

"When among the protectors of the world, he was the most honored among the protectors of the world, protecting all sentient beings." 'Protectors of the world' refers to the Four Heavenly Kings: in the east is Dhṛtarāṣṭra, who presides over two classes, gandharvas and piśācas; in the south is Virūḍhaka, who presides over two classes, kumbhāṇḍas and pretas; in the west is Virūpākṣa, who presides over two classes, nāgas and pūtanas; in the north is Vaiśravaṇa, who presides over two classes, yakṣas and rākṣasas. They protect all the worlds.
