 According to the Mulasarvastivada tradition, Uppalavanna had a tumultuous life as a wife and courtesan before converting to Buddhism and becoming a "bhikkhuni".Uppalavanna attained enlightenment while using a fire "kasina" as her object of meditation less than two weeks after her ordination.Following her enlightenment she developed a mastery of "iddhipada", or spiritual powers, leading the Buddha to declare her his female disciple foremost in psychic powers.
