Literally “Blue Throat,” he is associated with the legend of the churning of the great ocean. In the Buddhist context he is Vajrapāṇi, and in the Hindu context, Śiva. In the AP the name may refer to one of the lokeśvara emanations of Avalokiteśvara.

An epithet of Śiva (lit. “blue-throated one”), here apparently understood as a form of Avalokiteśvara. This epithet references the Purāṇic narrative in which Śiva drank the poison that arose when the gods churned the cosmic ocean, thus saving the world. Śiva did not die, but his neck turned blue. There are many parallels between Śiva and Avalokiteśvara, and here the text appears to explicitly understand Śiva as a form of Avalokiteśvara.
