In plain words
In the early part of the war, victory went to the Kauravas. The Pāṇḍavas, troubled, prayed to Kṛṣṇa. “Good meets with troubles at the start. Bad gives joy at the start. That lasts only a while, so go on doing your duty,” said Kṛṣṇa.
What is offered to God becomes inexhaustible
Once, while the Pāṇḍavas were in exile in the forest, Kṛṣṇa went to see them. The Pāṇḍavas told Him of their hardships. Dharmaja said, ‘We are men; we can bear any hardship and get through life. But Draupadī is a woman, and we cannot bear to see her enduring these hardships. Tell us some way out,’ he said. Kṛṣṇa took a leaf, wrote on it ‘They will not last for ever’, folded it carefully and gave it to Dharmaja. ‘Whatever hardships come to you, do not grieve; take out this leaf and look at it. Your troubles will be over,’ He said. One day Durvāsa went to Hastināpura to receive Duryodhana's hospitality. But there Duryodhana, with crooked intent, schemed that the Pāṇḍavas should fall victim to Durvāsa's anger, and sent Durvāsa to the Pāṇḍavas for hospitality. Durvāsa took all his people along and went to the Pāṇḍavas. He ordered them to have a meal ready for all his people by the time he came back from his bath, and went off to the river. The Pāṇḍavas had already finished their own meal. The akṣayapātra they had gives food only once a day. In this plight Dharmaja took out the leaf and looked at it. On it was written ‘They will not last for ever’. Draupadī prayed to Kṛṣṇa. Kṛṣṇa appeared and said, ‘I am hungry; is there anything to eat? Give it to me.’ He told them to look carefully into the akṣayapātra once, since there might be something in it. Then, seeing a bit of leaf in it, He ate it and said, ‘Akṣaya.’ Durvāsa and all his disciples, bathing in the river, found their hunger satisfied.
