King Jarāsandha was a very dutiful householder, and he had great respect for the brāhmaṇas. He was a great fighter, a kṣatriya king, but he was never neglectful of the Vedic injunctions. According to the Vedic injunctions, the brāhmaṇas are considered to be the spiritual masters of all other castes. Lord Kṛṣṇa, Arjuna and Bhīmasena were actually kṣatriyas, but they dressed themselves as brāhmaṇas, and at the time when King Jarāsandha was to give charity to the brāhmaṇas and receive them as guests, they approached him.
Lord Kṛṣṇa, in the dress of a brāhmaṇa, said to the King, "We wish all glories to Your Majesty. We three guests at your royal palace have come from a great distance to ask you for charity, and we hope that you will kindly bestow upon us whatever we ask from you. We know about your good qualities. A person who is tolerant is always prepared to tolerate everything, even though distressful. Just as a criminal can perform the most abominable acts, a greatly charitable person like you can give anything and everything for which he is asked. For a great personality like you, there is no distinction between relatives and outsiders. A famous man lives forever, even after his death; therefore, any person who is completely fit and able to execute acts which will perpetuate his good name and fame and yet does not do so becomes abominable in the eyes of great persons. Such a person cannot be condemned enough, and his refusal to give charity is lamentable throughout his whole life. Your Majesty must have heard the glorious names of charitable personalities such as Hariścandra, Rantideva and Mudgala, who used to live only on grains picked up from the paddy field, and the great Mahārāja Śibi, who saved the life of a pigeon by supplying flesh from his own body. These great personalities have attained immortal fame simply by sacrificing the perishable body." Lord Kṛṣṇa, in the garb of a brāhmaṇa, thus convinced Jarāsandha that fame is imperishable but the body is perishable. If one can attain imperishable name and fame by sacrificing his perishable body, he becomes a very respectable figure in the history of human civilization.
