Bhagavad Gita Chapter 2, Verse 38

सुखदुःखे समे कृत्वा लाभालाभौ जयाजयौ । ततो युद्धाय युज्यस्व नैवं पापमवाप्स्यसि ॥

sukha-duḥkhe same kṛtvā lābhālābhau jayājayau | tato yuddhāya yujyasva naivaṁ pāpam avāpsyasi ||

Regarding gain and loss, pleasure and pain, victory and defeat as all alike, make ready then for war. So shall no sin attain thee!

After offering Arjuna a win-win proposition in battle, Krishna now reveals the attitude that makes righteous action possible. Treat opposites—pleasure and pain, gain and loss, victory and defeat—with equal regard, then fight. This is samatva (equanimity): complete inner balance while performing your duty. You transcend sin not by avoiding action, but by transforming your relationship to outcomes. What matters isn't whether you win or lose, but whether you remain centered through both. This is how action becomes liberating rather than binding.
