Acting fully while releasing the claim on the result — the Gita's way to act in the world without being bound by it.
Common misconception
It does not mean acting carelessly or with no goals; it means not letting the fruit own your peace.
The question it leaves you holding
Can you give something your whole effort and still be unattached to how it turns out?
Schools that center this concept
Vishishtadvaita — Ramanuja's qualified non-dualism: souls and world are real, yet form the body of the one God they depend on.
Debates this concept decides
Act for the Duty, or for the Fruit? — The Gita says you have a right to action but never to its fruits. Can you truly act with full effort and zero attachment?
