Bhagavad Gita 3.9

यज्ञार्थात्कर्मणोऽन्यत्र लोकोऽयं कर्मबन्धन: |
तदर्थं कर्म कौन्तेय मुक्तसङ्ग: समाचार

Translation

Work must be done as a yajna to the Supreme Lord; otherwise, work causes bondage in this material world. Therefore, O son of Kunti, for the satisfaction of God, perform your prescribed duties, without being attached to the results.
