The Lord adds: Do your duty, for action is better than inaction. You have the right to fulfil your duties, but not to enjoy the fruits of your actions. Never think that you are the cause of the consequences of your actions, and at no time should you try to escape from your duty.
The individual spiritual being distinct from God is inspired to act in accordance with his position towards the Lord. Therefore, his victory or defeat depends entirely on the Supreme Person. We must be sincere, and act according to our position. Victory or defeat depends only on the Lord.
When Krishna desires, we are sure to be victorious. We should not be exuberant after victory, nor should we be distressed in defeat. We must make a sincere effort to do the will of Krishna, or Lord Chaitanya Mahaprabhu the Golden Avatar, without worrying about victory or defeat. The only duty we have is to act sincerely, so that our activities can be appreciated by Krishna.
The difference between the virtuous believers and the evil unbelievers is that the former know that nothing can happen unless the Sovereign Lord wants it to happen, while the latter cannot understand anything about the Supreme Will of God.
No one can act independently; on the contrary, everyone acts under the guidance of Krishna, God, the Supreme Person. Moreover, victory and defeat occur according to the consequences of karma, a divine law, a law of nature according to which every action, good or bad, necessarily entails consequences, which have the effect of chaining its author more and more to material existence and to the cycle of repeated deaths and rebirths or reincarnations. The Lord is the only judge in this matter.
Since we act under the dominion of the Supreme Being according to our karma, no one, from Brahma the first created being and demiurge of our galaxy, to the insignificant ant, is independent. Whether we are defeated or victorious, the Supreme Lord is always victorious, for all beings act under His guidance.
