Chapter 3 · Verse 17
Karma Yoga
कर्मयोग
In plain words
You are invited to find complete joy and satisfaction within your own inner self. When you attain jnana, which is spiritual wisdom, you no longer rely on external things for happiness. Having realized your true nature, you transcend the need for binding karma, or action, because you are already complete.
Translation
3.17 But the man whose delight is only in the self, who is satisfied with the self, who rejoices in the self, for him nothing remains to be accomplished.
Meaning
The sage does not depend on external objects for his happiness. He is ite satisfied with the Self. He finds his joy bliss and contentment within his own Self. For such a sage who has knowledge of the Self there is nothing to do. He has already done all actions. He has satisfied all his desires. He has complete satisfaction. (Cf. II.55).
Word by word
यः who तु but आत्मरतिः who rejoices in the Self एव only स्यात् may be आत्मतृप्तः satisfied in the Self च and मानवः the man आत्मनि in the Self एव only च and सन्तुष्टः contented तस्य his कार्यम् work to be done न not विद्यते is.
