Kassaka Sutta

Once the Buddha was at Sāvatthi preaching to the monks on nibbāna. Māra appears in the guise of a peasant, dishevelled, wearing hempen garments, with a mighty plough on his shoulder, and asks the Buddha if he has seen his oxen. The Buddha declares, unequivocally, that he has no eyes for things owned; having escaped completely from worldly desires, possessions and ownership, his mind furnishes no gateway for Māra. S.i.114.
