yajñārthāt karmaṇo ’nyatra loko ’yaṁ karma-bandhanaḥ tad-arthaṁ karma kaunteya mukta-saṅgaḥ samāchara
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.
Translated by Shri Purohit Swami
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.
Translated by Swami Sivananda
