Bhagavad Gita 18.59
यदहङ्कारमाश्रित्य न योत्स्य इति मन्यसे।मिथ्यैष व्यवसायस्ते प्रकृतिस्त्वां नियोक्ष्यति॥
yad ahankāram āśhritya na yotsya iti manyase mithyaiṣha vyavasāyas te prakṛitis tvāṁ niyokṣhyati
Translation
Entrenched in egoism, thou thinkest, "I will not fight;" to no purpose thy determination; nature will constrain thee.
What it means
Fixed in egoism you think "I will not fight"; vain is your resolve; your nature will compel you. The refusal cannot hold. What we are will eventually act through us, with or without consent.
Try this today
The prediction: Arjuna cannot actually abstain - his own nature will move him. Choice is real at a different level than he thinks.
Something to reflect on
Where am I vowing against my own nature - and who will win?
