The Yoga of Renunciation

Krishna describes the sages who attain liberation: those whose sins are destroyed (kṣīṇa-kalmaṣāḥ), whose dualities are cut off (chinnadvaidhāḥ), who have controlled the self (yatātmānaḥ), and who are engaged (ratāḥ) in the welfare of all beings (sarva-bhūta-hite). They attain (labhante) the nirvana of Brahman (brahma-nirvāṇam). This means the sages who attain liberation are those who have destroyed sins through knowledge, cut off dualities through equanimity, controlled the self through discipline, and are engaged in the welfare of all beings through selfless action. This is the complete picture of karma yoga—purification, equanimity, self-control, and selfless service. All four aspects are necessary for liberation.
