What is the right attitude? This verse is the most famous verse in the Bhagavad Gita and is said to summarize its essence: You have the right only to work, never to its result. Do not be one whose motive is the results of action.
Never be attached to inaction.
Do your duty, (Karthavyam), with the right attitude. Perform your actions, in a state of Yoga, having given up attachment and being the same in success or in the lack of it. Take refuge in the intellect. Stay always in Reality, regardless of your material well being. What is Yoga? Yoga is said to be Sameness (Equanimity). Yoga is skill in work.
Literally, Yoga means uniting. It can be uniting of the self with God, of the mind with the soul, or the body with mind and soul. It is derived from the verb root: Yuj or Yoke. When you are totally absorbed in your work or activity, your body and mind are united with your self and with God.
When you have the right attitude, you will be resolute. Then your effort will not be wasted. People motivated by results are miserable. Their body may be engaged in activity but their mind is focused on the results and they are ‘divided’ not ‘united’. Those who are focused on results, cannot do a good job because their mind is not where they are. They are not absorbed in their activity.
