A Nāga of Mañjerika. He was the nephew of Mahākāḷa, and when Soṇuttara went to the Nāga world to obtain the Buddha’s relics for the Mahā Thūpa, Mahākāḷa signed to Vāsuladatta to hide them. Vāsuladatta assumed a huge Nāga form, three hundred leagues long, with a head one league in extent, and having swallowed the casket containing the relics, lay down at the foot of Sineru. However, Soṇuttara, by his psychic power, put his hand into the Nāga’s stomach and removed the invisible relics. Mhv.xxxi.52 ff.
