Krishna introduces a massive philosophical exception to the rule of mandatory action. He says, 'yas tu' (but, on the other hand), there is a specific type of human being (mānavaḥ). This person takes delight entirely within the Self (ātma-ratiḥ), is fully satiated by the Self (ātma-tṛptaḥ), and is completely content in the Self alone (ātmany eva ca santuṣṭaḥ). For this extremely rare individual, Krishna declares: 'tasya kāryaṃ na vidyate' (for him, there is no prescribed duty).
