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 Harivamsa. This is in connection with Lord Krsna's fighting the King of heaven, Indra, who was forcibly deprived of the parijata flower. Parijata is a kind of lotus flower grown on the heavenly planets. Once, Satyabhama, one of Krsna's queens, wanted that lotus flower, and Krsna promised to deliver it; but Indra refused to part with his parijata flower. Therefore there was a great fight, with Krsna and the Pandavas on one side and all of the demigods on the other. Ultimately, Krsna defeated all of them and took the parijata flower, which He presented to His queen. So, in regard to that occurrence, Krsna told Narada 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 parijata flower, all the demigods-the Gandharvas, the Nagas, the demon Raksasas, the Yaksas, the Pannagas-tried to defeat Me, but none could make Me break My promise to My queen."
There is another promise by Krsna in the Bhagavad-gita 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 Krsna will never break His promise. He will always protect His devotees in every circumstance.
Krsna showed how He fulfills His promise by delivering the parijata flower to Satyabhama, by saving Draupadi from being insulted and by freeing Arjuna from the attacks of all enemies.
The promise of Krsna that His devotees are never vanquished had also previously been admitted by Indra when he was defeated in the Govardhana-lila. When Krsna stopped the villagers of Braja (Vrndavana) from worshiping Indra, Indra became angry and therefore inundated Vrndavana with continuous rain. Krsna, however, protected all of the citizens and animals of Vrndavana by lifting Govardhan Hill, which served as an umbrella. After the incident was over, Indra surrendered to Krsna with many prayers, in which he admitted, "By Your lifting Govardhan Hill and protecting the citizens of Vrndavana, You have kept Your promise that Your devotees are never to be vanquished."
