Chapter 3 · Verse 9
Karma Yoga
कर्मयोग
In plain words
You should perform all your daily tasks as a selfless offering to the Divine rather than for personal gain. When you do your karma, or action, with this attitude of bhakti, which means loving devotion, you remain free from the binding chains of the material world.
Translation
3.9 This world is held in the bondage of work only when work is not performed as sacrifice. O Arjuna, you must perform work to this end, free from attachment.
Meaning
Yajna means sacrifice or religious rite or any unselfish action done with a pure motive. It means also Isvara. The Taittiriya Samhita (of the Veda) says Yajna verily is Vishnu (174). If anyone does actions for the sake of the Lord he is not bound. His heart is purified by performing actions for the sake of the Lord. Where this spirit of unselfishness does not govern the action it will bind one to Samsara however good or glorious it may be. (Cf. II.48).
Word by word
यज्ञार्थात् for the sake of sacrifice कर्मणः of action अन्यत्र otherwise लोकः the world अयम् this कर्मबन्धनः bound by action तदर्थम् for that sake कर्म action कौन्तेय O Kaunteya मुक्तसंगः free from attachment समाचार perform.
