Meanwhile the Vrjian monks of Vaiśālī had heard rumours about the doings of Yaśas, and being convinced that the opinion of Revata would carry great weight, they decided upon trying to gain him over to their party.

His doubts were happily soon dissipated by a heavenly being, to whom he promised to make manifest his opinion when needed.
