In Bhagavad-Gita Lord krishna says, kaunteya pratijanihi na me bhakta pranasyati: "My dear Arjuna, you may declare to the word that my devotee is never vanquished." Now, one may ask, why did krishna advise Arjuna to declare this? Why did he not declare it himself? The answer is that if krishna Himself made this declaration, it might be suspect, because krishna sometimes violate His own promise. But the promise of a devotee will never be violated. This is krishna concern. "Oh, my devotee has declared this. I must see that his words are kept." This is krishna's position because of his affection for His devotees. Therefore lord krishna said, you declare it. If I declare it, people may not believe it, but if you declare it they will believe you because you are my devotee." Even though Krishna may break His own promise, He want to see that the promises of his devotees are fulfilled.
Therefore, we must take to Krishna consciousness and adhere to this consciousness under all circumstances, even in the most dangerous position. We must keep our faith in Krishna's lotus feet, and then there will be no danger.
