The Noble Great Vehicle Sūtra “The Questions of the Nāga King Sāgara”

The Questions of the Nāga King Sāgara begins with a miracle that portends the coming of the Nāga King Sāgara to Vulture Peak Mountain in Rājagṛha. The nāga king engages in a lengthy dialogue with the Buddha on various topics pertaining to the distinction between relative and ultimate reality, all of which emphasize the primacy of insight into emptiness. The Buddha thereafter journeys to King Sāgara’s palace in the ocean and reveals details of the king’s past lives in order to introduce the inexhaustible casket dhāraṇī. In the nāga king’s palace in the ocean, he gives teachings on various topics and acts as peacemaker, addressing the ongoing conflicts between the gods and asuras and between the nāgas and garuḍas. Upon returning to Vulture Peak, the Buddha engages in dialogue with King Ajātaśatru and provides Nāga King Sāgara’s prophecy.
