Another instance of Kṛṣṇa's feeling of obligation is stated in connection with His dealings with Jāmbavān. When the Lord was present as Lord Rāmacandra, Jāmbavān, the great king of the monkeys, rendered very faithful service to Him. When the Lord again appeared as Lord Kṛṣṇa, He married Jāmbavān's daughter and paid him all the respect that is usually given to superiors. Any honest person is obliged to his friend if some service has been rendered unto Him. Since Kṛṣṇa is the supreme honest personality, how can He forget an obligation to His servitor?
Any person who observes regulative principles and fulfills his promises by practical activity is called determined. As far as the Lord's determination is concerned, there is an example in His dealings in the Harivaṁśa. This is in connection with Lord Kṛṣṇa's fighting the King of heaven, Indra, who was forcibly bereft of the pārijāta flower. Pārijāta is a kind of lotus flower grown on the heavenly planets. Once, Satyabhāmā, one of Kṛṣṇa's queens, wanted that lotus flower, and Kṛṣṇa promised to deliver it; but Indra refused to part with his pārijāta flower. Therefore there was a great fight, with Kṛṣṇa and the Pāṇḍavas on one side and all of the demigods on the other. Ultimately, Kṛṣṇa defeated all of them and took the pārijāta flower, which He presented to His queen. So, in regard to that occurrence, Kṛṣṇa told Nārada Muni, "My dear great sage of the demigods, now you can declare to the devotees in general, and to the nondevotees in particular, that in this matter of taking the pārijāta flower, all the demigods—the Gandharvas, the Nāgas, the demon Rākṣasas, the Yakṣas, the Pannagas—tried to defeat Me, but none could make Me break My promise to My queen."
There is another promise by Kṛṣṇa in the Bhagavad-gītā to the effect that His devotee will never be vanquished. So a sincere devotee who is always engaged in the transcendental loving service of the Lord should know for certain that Kṛṣṇa will never break His promise. He will always protect His devotees in every circumstance.
Kṛṣṇa showed how He fulfills His promise by delivering the pārijāta flower to Satyabhāmā, by saving Draupadī from being insulted and by freeing Arjuna from the attacks of all enemies.
The promise of Kṛṣṇa that His devotees are never vanquished had also previously been admitted by Indra when he was defeated in the Govardhana-līlā. When Kṛṣṇa stopped the villagers of Braja (Vṛndāvana) from worshiping Indra, Indra became angry and therefore inundated Vṛndāvana with continual rain. Kṛṣṇa, however, protected all of the citizens and animals of Vṛndāvana by lifting Govardhan Hill, which served as an umbrella. After the incident was over, Indra surrendered to Kṛṣṇa with many prayers, in which he admitted, "By Your lifting Govardhan Hill and protecting the citizens of Vṛndāvana, You have kept Your promise that Your devotees are never to be vanquished."
