An arahant. He was originally a very poor man. A monk of
Jetavana, seeing him clad in a loin cloth, carrying a plough on his shoulder,
suggested to him that he should become a monk. He was ordained, and, at his
teacher's suggestion, hung his loin cloth and plough on a tree near the
monastery. He was called Napgalakula (ploughman) on account of his former
calling. Whenever he felt discontented with monastic life, he would go to the
tree and blame himself for his shamelessness in harbouring thoughts of returning
to his former life. On being asked where he went, he would say "to my teacher."
One day he became an arahant, and when asked why he no longer went to his
teacher, he answered that the need was no more. This was reported to the Buddha,
who praised the monk for his self-admonition. DhA.iv.115 17.
