One of the sixteen disciples of Bāvarī, who, at his request, visited the Buddha (SN.vs.1008).
He questioned the Buddha as to how a man could get over attachment and cross the flood. By grasping after nothing in the world, answered the Buddha, for Māra follows the man who clings to things.
This question and answer are contained in the Bhadrāvudhamānava-puccha (SN.vs.1101-4), which is explained in the Culla Niddesa (CNid.36f).
At the end of the discourse, Bhadrāvudha and his pupils became arahants and joined the Order. SNA.ii.599.
