Nanda Jataka While residing at Jetavana the Buddha told this story about Sariputta's pupil who was his co-resident. As the story goes this pupil was gentle and tractable and he was ardent in serving Sariputta. On a certain occasion Sariputta with the Buddha's permission went on an alms-pilgrimage and he eventually came to South Magadha. His pupil who accompanied him was overcome by pride and would not do what he told him. Whenever the pupil was addressed: "Sir, do this," he would start a quarrel and Sariputta could not make out what had possessed him. After his pilgrimage round Sariputta returned to Jetavana with his pupil. The moment they got back to the monastery that pupil became his usual placid self. Sariputta reported this matter to the Buddha.
