Krishna states a stark, undeniable biological and physical law. For anyone who possesses a physical body (deha-bhṛtā), it is absolutely impossible (na hi śakyaṁ) to give up all activities entirely (tyaktuṁ karmāṇy aśeṣataḥ). Because physical inaction is impossible, Krishna gives the final definition: the person who successfully renounces the *fruits* of their inevitable actions (yas tu karma-phala-tyāgī) is the one who is officially declared to be the true renouncer (sa tyāgīty abhidhīyate).
