Treating pleasure and pain, gain and loss, victory and defeat alike, prepare for battle. Thus you will not incur sin.

Kṛṣṇa introduces samatva — equanimity — as the fundamental attitude of yoga.

Three pairs of opposites (dvandvas):

• Sukha-duḥkha — pleasure and pain
• Lābha-alābha — gain and loss
• Jaya-ajaya — victory and defeat

Same kṛtvā — making them equal, treating them with the same attitude. This doesn’t mean insensitivity but non-attachment to results.

Yuddhāya yujyasva — prepare for battle. Yuj is the root of “yoga”: joining action with equanimity.

Naivaṃ pāpam avāpsyasi — thus you will not incur sin. Sin (pāpa) doesn’t come from the action itself, but from selfish attachment to results.

In daily life: act fully, give your best effort, but don’t define yourself by the results. This attitude frees action from the weight of the ego.
