A Nága of Mańjerikabhavana. He was the nephew of Mahákála, and when Sonuttara went to the Nága world to obtain the Buddha's relics for the Mahá Thúpa, Mahákála signed to Vásuladatta to hide them. Vásuladatta assumed a huge Nága 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. But Sonuttara, by his iddhi power, put his hand into the Nága's stomach and removed the invisible relics. Mhv.xxxi.52ff.
