Bhagavad Gita 18.6

एतान्यपि तु कर्माणि सङ्गं त्यक्त्वा फलानि च।कर्तव्यानीति मे पार्थ निश्िचतं मतमुत्तमम्॥

etānyapi tu karmāṇi saṅgaṃ tyaktvā phalāni ca |kartavyānīti me pārtha niśिcataṃ matamuttamam ||

But even these actions should be performed, leaving aside attachment and the desire for rewards, O Arjuna; this is my certain and most assured conviction.

But they should be done with detachment and without thought of reward. This is my final judgement.

Our plain-language meaning of this verse is waiting for scholar review.
