Śaṅkarācārya's commentary

Standing firm in this Yoga, perform thy works, casting off all attachment to their fruits. Be the same in success and failure — in attainment and non-attainment of the desired result. This evenness of mind (samatva) is what is here called Yoga. The Yoga of works is not a particular act but the inner orientation of evenness: he who acts thus is yoked (yukta) even in the midst of action.
