The Yoga of Liberation by Renunciation

This verse addresses potential hesitation: if, taking refuge in ego, you think 'I will not fight' (yad ahaṅkāram āśritya na yotsya iti manyase), that resolve of yours is false. Your nature will compel you (mithyaiṣa vyavasāyas te prakṛtis tvāṁ niyokṣyati). This is the key teaching: if you think you can avoid action by relying on ego, that resolve is false. Your nature will compel you to act. You cannot escape action through ego—nature will force you to act. This emphasizes that you should perform action as your duty, not try to avoid it through ego. The only way to be free is through unattached action, not through ego-based avoidance. When you understand this, you realize: you don't need to try to avoid action through ego. Your nature will compel you to act anyway. You can perform action as your duty with unattached action, which leads to freedom. This is the path: perform action as duty with unattached action, not avoid it through ego.
