Krishna calls out Arjuna's bluff. He says, 'If, taking shelter of your false ego (yad ahaṅkāram āśritya), you proudly think to yourself, "I shall not fight" (na yotsya iti manyase), your resolve is completely false and useless (mithyaiṣa vyavasāyas te). Why? Because your own inherent material nature (prakṛtis tvāṁ) will physically force you to engage in warfare anyway (niyokṣyati).'
