Bhagavad Gita Verse 3.19

इसलिये तू निरन्तर आसक्तिसे रहित होकर सदा कर्तव्यकर्मको भलीभाँति करता रह क्योंकि आसक्तिसे रहित होकर कर्म करता हुआ मनुष्य परमात्माको प्राप्त हो जाता है|

Therefore, Arjuna always perform your given duties without feelings of attachment towards any being or anything. A person doing unattached actions, or in other words, “inction” attains the Lord, the key to perfection.
