यदहङ्कारमाश्रित्य न योत्स्य इति मन्यसे।
मिथ्यैष व्यवसायस्ते प्रकृतिस्त्वां नियोक्ष्यति।।18.59।।
18.59 That you think I shall not fight, by relying on egotism,-vain is this determination of yours. (Your) nature impel you!
18.59 If, in your self-conceit, i.e., under a false sense of independence that you know what is good for you and what is not - if, not heeding My ?nd, you think, I will not fight, then this resolve based on your sense of independence will be in vain. For Nature will compel you to go against your resolve - you who are ignorant and who adversely react to my sovereignty. He elucidates the same:
Yadahankaaram aashritya na yotsya iti manyase; Mithyaisha vyavasaayaste prakritistwaam niyokshyati.
yat—if; ahankāram—motivated by pride; āśhritya—taking shelter; na yotsye—I shall not fight; iti—thus; manyase—you think; mithyā eṣhaḥ—this is all false; vyavasāyaḥ—determination; te—your; prakṛitiḥ—material nature; tvām—you; niyokṣhyati—will engage
