Bhagavad Gita 3.9

यज्ञार्थात्कर्मणोऽन्यत्र लोकोऽयं कर्मबन्धनः।तदर्थं कर्म कौन्तेय मुक्तसंगः समाचर॥

yajñārthātkarmaṇo'nyatra loko'yaṃ karmabandhanaḥ |tadarthaṃ karma kaunteya muktasaṃgaḥ samācara ||

The world is bound by actions other than those performed for the sake of sacrifice; do thou, therefore, O son of Kunti (Arjuna), perform actions for that sake alone, free from attachment.

In this world, people are fettered by their actions, unless they are performed as a sacrifice. Therefore, O Arjuna, let your actions be done without attachment, as a sacrifice only.

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