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."
19. Expert Judge of Time and Circumstances
Kṛṣṇa was very expert in dealing with people according to circumstances, country, time and paraphernalia. How He could take advantage of a particular time, circumstance and person is expressed by Him while talking to Uddhava about His rāsa dance with the gopīs. He says: "The most opportune time is the full moon night in autumn, like tonight. The best place within the universe is Vṛndāvana, and the most beautiful girls are the gopīs. So, My dear friend Uddhava, I think I should now take advantage of all these circumstances and engage Myself in the rāsa dance."
20. Seer by the Authority of the Scriptures
A person who acts exactly according to the tenets of scripture is called śāstra-cakṣus. Śāstra-cakṣus means one who sees through the eyes of the authorized scriptures. Actually, any man of knowledge and experience should see everything through these books. For example, with our naked eye we perceive the sun globe simply as some glaring substance, but when we see through authorized books of science and other literature, we can understand how much greater the sun globe is than this earth and how powerful it is. So seeing things through the naked eye is not actually seeing. Seeing things through the authorized books or authorized teachers is the correct way to see. So, although Kṛṣṇa is the Supreme Personality of Godhead and can see all that is past, present and future, to teach the people in general He used to always refer to the scriptures. For example, in the Bhagavad-gītā, although Kṛṣṇa was speaking as the supreme authority, He still mentioned and quoted Vedānta-sūtra as authority. There is a statement in the Śrīmad-Bhāgavatam wherein a person jokingly says that Kṛṣṇa, the enemy of Kaṁsa, is known as the seer through the śāstras. In order to establish His authority, however, He is now engaged in seeing the gopīs, whereby the gopīs are becoming maddened.
