 In Buddhist belief, when a fully enlightened Buddha appears in the world, he always has a set of chief disciples.For the current Buddha, Gautama, his chief male disciples were Sariputta and Moggallana, while his chief female disciples were Khema and Uppalavanna.According to Theravada commentaries, in a previous life Khema was born a woman in the time of Padumattara Buddha and encountered Padumattara Buddha's chief male disciple foremost in wisdom.
