In plain words
Individual freedom is one thing; Fundamental Law is another. "This is a matter that belongs to the kingdom, so, whatever it may be, give Me a service," Kṛṣṇa said. Then Dharmaja said, "Brother-in-law! Whatever You like, take that." "I do not need to ask you in order to take what I like. Tell Me what task you would like, and I will do it," He said. In the end the argument between the two wasted the time. Not to waste the time, Kṛṣṇa said He was ready to wash the feet of all the scholars who had come and to welcome them Himself. Here is a fine ideal for rooting out Ahaṅkāra. An ideal that raises man is most needed here. We must not wonder whether Śrī Kṛṣṇa, so mighty, should enter into so small a task. One who is a leader must himself lead in everything. To show men the ideal, Kṛṣṇa gave this kind of ideal in every field and in every matter. Out of His Prema for the Pāṇḍavas, and so that their brotherhood should not be broken, He protected them many times and showed an ideal of this kind.
Before the war, all agreed to send Kṛṣṇa as their envoy. The close bond between Kṛṣṇa and the Pāṇḍavas was one where heart was joined to heart. It was not a bond joined merely by kinship, or by politics. As much Prema as Kṛṣṇa had for the Pāṇḍavas, so much Prema the Pāṇḍavas too had for Kṛṣṇa. There was no help for it: they could send no one but Kṛṣṇa. So He reached Hastināpura as the envoy of the Pāṇḍavas. To welcome Kṛṣṇa, Duryodhana, Duśśāsana and the rest, in a crooked love full of plotting, laid out many kinds of splendour. As Kṛṣṇa stepped down from the chariot, Duryodhana and Duśśāsana begged Him to stay in their own guest house and to accept their hospitality. There too He taught the brothers statecraft well. "Duśśāsana! I have come as an envoy. Only after My task is done will I be your guest; until then I cannot stay," He said. "Only after this bears fruit will I eat the feast," He said. "Before that I cannot accept your guest house or your feast," He said. Having said this sternly and brought statecraft to their notice, He went to Vidura's house. Just as ordinary people imagine today, Vidura too was misled in the same way. "Kṛṣṇa, You who know all and are all power, how did You agree to so small a task? How did the Pāṇḍavas send You? The Kauravas are very wicked. With their evil minds they can weave many schemes and subject You to every kind of violence. Knowing all this, how did You come here?" he said.
