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 temporary and 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.
While Lord Kṛṣṇa was speaking in the garb of a brāhmaṇa along with Arjuna and Bhīma, Jarāsandha marked that the three of them did not appear to be actual brāhmaṇas. There were signs on their bodies by which Jarāsandha could understand that they were kṣatriyas. Their shoulders were marked with impressions due to carrying bows, they had beautiful bodily structure, and their voices were grave and commanding. Thus he definitely concluded that they were not brāhmaṇas but kṣatriyas. He also thought that he had seen them somewhere before. But although these three persons were kṣatriyas, they had come to his door begging alms like brāhmaṇas. Therefore he decided that he would fulfill their desires in spite of their being kṣatriyas, because they had already diminished their position by appearing before him as beggars. “Under the circumstances,” he thought, “I am prepared to give them anything. Even if they ask for my body, I shall not hesitate to offer it to them.” In this regard, he began to think of Bali Mahārāja. Lord Viṣṇu in the dress of a brāhmaṇa appeared as a beggar before Bali and snatched away all of his opulence and his kingdom. He did this for the benefit of Indra, who, having been defeated by Bali Mahārāja, was bereft of his kingdom. Although Bali Mahārāja was cheated, his reputation as a great devotee able to give anything and everything in charity is still glorified throughout the three worlds. Bali Mahārāja could guess that the brāhmaṇa was Lord Viṣṇu Himself and had come to him just to take away his opulent kingdom on behalf of Indra. Bali’s spiritual master and family priest, Śukrācārya, repeatedly warned him about this, yet Bali did not hesitate to give in charity whatever the brāhmaṇa wanted, and at last he gave up everything to that brāhmaṇa. “It is my strong determination,” thought Jarāsandha, “that if I can achieve immortal reputation by sacrificing this perishable body, I must act for that purpose; the life of a kṣatriya who does not live for the benefit of the brāhmaṇas is certainly condemned.”
Actually King Jarāsandha was very liberal in giving charity to brāhmaṇas, and thus he informed Lord Kṛṣṇa, Bhīma and Arjuna: “My dear brāhmaṇas, you may ask from me whatever you like. If you so desire, you may take my head also. I am prepared to give it.”
After this, Lord Kṛṣṇa addressed Jarāsandha as follows: “My dear King, please note that we are not actually brāhmaṇas, nor have we come to ask for food or grain. We are all kṣatriyas, and we have come to beg a duel with you. We hope that you will agree to this proposal. You may note that here is the second son of King Pāṇḍu, Bhīmasena, and the third son of Pāṇḍu, Arjuna. As for Myself, you may know that I am your old enemy Kṛṣṇa, the cousin of the Pāṇḍavas.”
When Lord Kṛṣṇa disclosed their disguise, King Jarāsandha laughed very loudly, and then in great anger and in a grave voice he exclaimed, “You fools! If you want to fight with me, I immediately grant your request. But, Kṛṣṇa, I know that You are a coward. I refuse to fight with You because You become very confused when You face me in fighting. Out of fear of me You left Your own city, Mathurā, and now You have taken shelter within the sea; therefore I must refuse to fight with You. As far as Arjuna is concerned, I know that he is younger than me and is not an equal fighter. I refuse to fight with him because he is not in any way an equal competitor. But as far as Bhīmasena is concerned, I think he is a suitable competitor to fight with me.” After speaking in this way, King Jarāsandha immediately handed a very heavy club to Bhīmasena, he himself took another, and all of them went outside the city walls to fight.
