The Yoga of Action

After verse 3.31's promise of freedom to faithful practitioners, Krishna warns of the opposite path: those who criticize without trying—'abhyasūyantaḥ' (finding fault) yet 'nānutiṣṭhanti' (don't practice). They become 'sarva-jñāna-vimūḍhān'—deluded about all knowledge, thinking they're wise when they're actually confused because they never engaged. 'Naṣṭān acetasaḥ'—lost and without discrimination. Acetasaḥ means unable to discern truth. The teaching is sharp: sideline criticism without practice equals delusion and lostness.
