Bhagavad Gita Verse 4.22

जो बिना इच्छाके अपने-आप प्राप्त हुए पदार्थमें सदा सन्तुष्ट रहता है, जिसमें ईर्ष्याका सर्वथा अभाव हो गया है, जो हर्ष-शोक आदि द्वन्द्वों से सर्वथा अतीत हो गया है- ऐसा सिद्धि और असिद्धिमें सम रहनेवाला कर्मयोगी कर्म करता हुआ भी उनसे नहीं बँधता|

A person who is content with what he has who has no feeling of desire for other things, or uncertainty of any type, who has shed his envious feelings and who is above all even-minded in success and failure, such a person is no longer bound by Karma even if he still performs Karma.
