Lord Kṛṣṇa said . . . as the Supreme Lord, He commanded—He has got the commanding power because He is the Supreme God—that, "You surrender unto Me." Just like some superior, the teacher or father or king, says: "You must do it." But there is force. The State says: "You must do it," but if you do not do it, then there is force. Just like this draft board. They are demanding that, "You must join. If you don't join, there will be force, and you will be forcibly joined after that."
So here, in the Kṛṣṇa's order, because He is Kṛṣṇa, the Supreme Lord, there is no force. That voluntary. He says that, "This is life—you surrender unto Me." But He could force Arjuna to surrender, or anybody, because He is Supreme Lord. But that force He does not apply, because He has given us little independence. Therefore, if He forces, then His gift of independence is misused from His side. We are misusing our that gift of independence, but for that reason, Kṛṣṇa cannot withdraw your independence.
