Now, we have to dovetail ourself with that plan of the Supreme Lord. That is called karma-yoga. That is called karma-yoga. So Arjuna understood it, and he dovetailed himself with the supreme will of the Lord. And when he was inquired, "Whether you are going or fight or not? What you have settled after hearing Bhagavad-gītā?" he said, "Yes Kṛṣṇa. My illusion is now removed by Your grace, and I have decided to fight. That's all."
Now, that agreement of fighting and in the beginning of Bhagavad-gītā, not to fight, that is the difference. In the beginning he was not in agreement with Kṛṣṇa. He made so many arguments with Kṛṣṇa against fighting. And at the end, he agreed. "Yes," he said. He became a yes man. So we have to become a yes man to the Supreme Lord. That's all. That is the perfection of our spiritual life. Now we are all "no men." God says this, I say "no." Stubborn. I say, "no." Now simply we have to say "yes". That's all. In everything we say, "no" at the present. Present formation of our existence is to say "no." Anything godly, we say "no." We shudder even by the name of God. We have come to a certain stage of our civilized life, that we want to banish God altogether. Not only saying "no," but we now prepare to agree to the point that there is no existence of God. So how much foolish we are becoming day by day in the name of advancement of civilization. You see?
