This story illustrates the devotion of an aarkt devotee.
Draupadi was the daughter of king Drupad and was born as a result of a yagna. She was very beautiful, talented, devoted to her husband, ideal housewife and a true devotee of God. She considered Krishna as the supreme God and Krishna too didn't hide his supreme powers from her. On the orders of Duryodhan, Dushasan tried to insult her by dragging her in front of everybody in the court and unwrapping her saree. Seeing that no one was coming to her rescue, Draupadi found herself totally helpless and prayed to Krishna. She believed that on hearing her faithful plea, Krishna would definitely come to save her. When Krishna heard her prayers he took the form of her cloth. So that her saree became a never ending piece of cloth. Hence, by being there at the right time Krishna saved Draupadi from the humiliation and Dushasan finally got tired and gave up.
