The Lord awakens in the minds of the people faith in and reverence for the Vedas and other sacred scriptures, the other world, saints and God by carrying out the injunctions of the scriptures in His own personal life,and demonstrating the glory of righteousness by the use of His inspiring and powerful words and messages, and developing among the people a natural love and reverence for virtues and right conduct, makes them strongly cling to them.
He reveals a simple way for salvation.
Lord Krishna says to Arjuna: " Resigning all your duties to Me, the all-powerful and all-supporting Lord, take refuge in Me alone. I shall absolve you of all sins, worry not" (Gita chapter 18, verse 66)
Krishna thus concludes his teaching of the Gita by giving a promise to the entire mankind.
And God has never broken any promise ever spoken.
