Kṛṣṇa gives a staggering spiritual formula: if a person is free from the ego of ‘doership’ (‘nāhaṅkṛto bhāvo’) and his intelligence is not entangled in the material world, then even if he performs a seemingly violent act (like killing in a war), he does not ‘kill’ in the karmic sense. He is not bound by the reactions of his actions. This is the core of Arjuna’s solution. Since he is fighting as an instrument of God, without personal pride or desire for the kingdom, the act of fighting becomes ‘A-karma’—action without reaction. It is like a judge who sentences a criminal to death; the judge isn’t a murderer because he is acting as an instrument of the law, not out of personal anger. Arjuna is being asked to act as the instrument of Divine Law. It teaches us that our ‘Internal State’ determines our karma, not the external act. If we do our duty with a surrendered heart and no ego, we remain clean. We should work to remove the ‘I’ from our actions. By shifting our identity from ‘Owner’ to ‘Instrument’, we find the ultimate safety. We can act dynamically in the world while staying completely free from the chains of karma.
