The Kauravas had also based their strength on military might. In the end, all these brothers died in the war which they had fomented and not even a single son was left to perform the funeral rites for the parents, when the parents died. What a terrible fate that was. Instead of seeking divine help, the Kaurava brothers took refuge only in physical power, in money and in the strength of individuals. On the other hand, the Pandava brothers surrendered everything to Krishna, and sought only his grace.
Real power lies in faith.
He assured Arjuna on the day of the battle that whoever takes refuge in the Lord will win the Grace of the Lord, and will be successful in whatever he undertakes. Whereas one who refuses the protection of the Lord will not be able to win his grace, and in the end, will surely fail and be destroyed. If you aspire to earn the grace of the Lord, you have to control your worldly desires. All your activities in the phenomenal world have to do with the waking state. The results that arise from these activities are no more real than the results you get in dreams.
