Bhagavad Gita 2.38
सुखदुःखे समे कृत्वा लाभालाभौ जयाजयौ। ततो युद्धाय युज्यस्व नैवं पापमवाप्स्यसि॥
sukha-duḥkhe same kṛitvā lābhālābhau jayājayau tato yuddhāya yujyasva naivaṁ pāpam avāpsyasi
Translation
Taking as equal pleasure and pain, gain and loss, victory and defeat, gird thee for the battle; thus thou shalt not incur sin.
What it means
Holding pleasure and pain, gain and loss, victory and defeat as equal, then fight; so you incur no sin. This is the hinge verse: equality of mind is what purifies action, not withdrawal from it.
Try this today
The seed of karma yoga: equal-mindedness about outcomes frees action from contamination.
Something to reflect on
Can I commit fully to this while holding win and loss in the same hand?
