श्री भगवानुवाच संन्यासः कर्मयोगश्च निःश्रेयसकरावुभौ। तयोस्तु कर्मसंन्यासात्कर्मयोगो विशिष्यते ॥

sannyāsaḥ karma-yogaśh cha niḥśhreyasa-karāvubhau tayos tu karma-sannyāsāt karma-yogo viśhiṣhyate

Renunciation and yoga by action both lead to the highest bliss; of the two, yoga by action is verily better than renunciation of action.

In plain words: Krishna answers that both giving up action and doing action as yoga lead to the highest joy. But doing your work in the spirit of yoga is better than giving up work.
