首楞嚴義疏注經 6.48

6.48

天王太子，即那吒之類。輔政統攝，跨握鬼物，護世益人。菩薩身同，先令成就，後使厭離。

A prince of a heavenly king is of the kind like Nata. Assisting governance and taking command, grasping and controlling ghostly beings, they protect the world and benefit people. The Bodhisattva assumes the same body, first causing them to achieve [their wish], and later making them weary [of it] and renounce it.
