2.107

什曰：護世，四天王也。諸惡鬼神殘食眾生，護世四王護之，不令害也。今言尊者道力所護兼及十方也。肇曰：護世四王各治一方，護其所部，使諸惡鬼神不得侵害也。

[Kumāra]jīva says: The world-protectors are the Four Heavenly Kings. Various evil ghosts and spirits prey upon sentient beings, and the four guardian kings of the world protect them, not allowing them to do harm. Here, saying he is 'honored' means that what is protected by his spiritual power reaches across the ten directions. [Seng]zhao says: The four guardian kings of the world each govern one direction, protecting their own domain so that evil ghosts and spirits cannot harm them.
