The Yoga of Renunciation

Krishna describes the yogi's ability: one who is able (śaknoti) to withstand (soḍhum) the urge (vegam) born of desire and anger (kāma-krodhodbhavam) here itself (iha eva), before giving up the body (prāk śarīra-vimokṣaṇāt), is a yogi (sa yuktaḥ), and he is a happy person (sa sukhī naraḥ). This means the yogi doesn't wait for death to overcome desire and anger—they overcome them while living. The ability to withstand the impulses born of desire and anger is the mark of a yogi. This is the practical test of karma yoga—can you withstand the urges of desire and anger while performing your duties? If you can, you're a yogi and you're happy.
