4.22 Content with whatever chance may bring for the maintenance of the body; rising above the pairs of opposites means enduring cold, heat and such other experiences until one has completed the practice of Karma Yoga; free from ill-will? i.e., free from ill-will towards others, seeing his own Karma as the cause of his adversity; even-minded in success and failure, i.e., even-minded at success like victory in war, etc., and failure therein - such a person is not bound, i.e., he does not fall into Samsara, though devoted to action without any exclusive practice of Jnana Yoga.
