He made a mental vow to punish the arrogant king for this insult and his repudiation of the sacred claims of early friendship. His next move in search of employment was to go to Hastinapura, where he spent a few days, in retirement, in the house of his brother-in-law Kripacharya. One day, the princes were playing with a ball outside the precincts of the city, and in the course of the game, the ball as well as Yudhishthira's ring fell into a well. The princes had gathered round the well and saw the ring shining from the bottom through the clear water. But could see no way of getting it out. They did not however, notice that a brahmana of dark complexion stood nearby watching them with a smile. "Princes," he surprised them by saying, "you are the descendants of the heroic Bharata race. Why cannot you take out the ball as anyone skilled in arms should know how to do? Shall I do it for you?" Yudhishthira laughed and said in fun: "O brahmana, if you take out the ball, we will see that you have a good meal in the house of Kripacharya." Then Drona the brahmana stranger, took a blade of grass and sent it forth into the well after reciting certain words of power for propelling it as an arrow. The blade of grass straightway sped and stuck into the ball. Afterwards he sent a number of similar blades in succession which clinging together formed a chain, wherewith Drona took out the ball. The princes were lost in amazement and delight and begged of him to get the ring also.
