18.59. In case, holding fast to the sense of ego, you think (decide) ‘I shall not fight’, that resolve of yours will be just useless. [For] your own natural condition will incite you [to fight].
Shri Purohit Swami
18.59 If thou in thy vanity thinkest of avoiding this fight, thy will shall not be fulfilled, for Nature herself will compel thee.
Sri Abhinav Gupta
18.59 See Comment under 18.60
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:
18.59 Yat, that; manyase, you think, resolve; this-’na yotsye, I shall not fight’; asritya, by relying; on ahankaram, egotism, mithya, vain; is esah, this; vyava-sayah, determination; te, of yours; because prakrtih, nature, your own nature of a Ksatriya; niyoksyati, will impell; ;tvam, you!
18.59 If, in your self-conceit, you think, ‘I will not fight,’ your resolve is in vain. Nature will compel you.
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, filled with egoism, thou thinkest: “I will not fight”, vain is this, thy resolve; Nature will compel thee.
18.59 यत् if? अहङ्कारम् egoism? आश्रित्य having taken refuge in? न not? योत्स्ये (I) will fight? इति thus? मन्यसे (thou) thinkest? मिथ्या vain? एषः this? व्यवसायः resolve? ते thy? प्रकृतिः nature? त्वाम् thee? नियोक्ष्यति will compel.Commentary This strong determination of thy mind will be rendered utterly futile by thy inner nature thy nature will constrain thee thy nature as a warrior will compel thee to fight. It is a mere illusion to say that thou art Arjuna? that these are thy relatives and that to kill them will be a sin.
