Bhagavad Gita 5.12

युक्त: कर्मफलं त्यक्त्वा शांतिमाप्नोति नैष्ठिकम् | अयुक्तः कामकारेण फले सक्तो निबध्यते

Translation

Offering the results of all activities to God, the karm yogis attain everlasting peace. Whereas those who, being impelled by their desires, work with a selfish motive become entangled because they are attached to the fruits of their actions.
