Krishna has just described those who live by his teaching as wise; now he turns to what happens in those who don't, tracing how the refusal to act from clear understanding ripples outward into collapse.
ye tv etad abhyasūyanto nānutiṣṭhanti me matam | sarva-jñāna-vimūḍhāṃs tān viddhi naṣṭān acetasaḥ ||
But those who find fault with this teaching and do not follow it, know them to be deluded in all knowledge, lost, and without discernment.
The verse begins with abhyasūyā, that specific quality of hostile fault-finding. Krishna is pointing at something psychologically precise: resentment toward a teaching actively prevents learning from it. You cannot absorb what you are busy pushing away. The emotion forecloses the inquiry before it begins.
Not following through on what you understand is itself a kind of confusion. The verse does not say these people are unintelligent. It says they do not act on what they know. That gap, between understanding and action, is where the damage actually happens. The knowing that is never tested in action quietly decays.
Sarva-jñāna-vimūḍha is the diagnosis: confused in all knowing, not just some of it. A single refused truth, held in place long enough, tends to recruit everything else around it. The mind reorganizes to protect the refusal. What starts as one blind spot can end up shaping the entire perceptual field.
The word naṣṭa (lost) carries no agent. Nobody is punishing these people. The loss is structural, the natural consequence of running an instrument consistently against its own function. A compass used to point away from north is still a compass; it just no longer tells you anything useful about where you are.
Person A has read about cognitive bias, talks about it fluently, even teaches it to others. But when their own decisions are questioned, they get irritable and dismissive. They have the information; they just refuse to let it apply to themselves. The knowledge stays ornamental. Over years, their judgment in the very domain they claim expertise gets worse, not better, because the feedback loop is never honestly closed. Person B hits the same information and feels the same irritation initially. But they sit with the discomfort long enough to ask whether the irritation means something. They start actually using what they know. Their blind spots shrink slowly. They are not more talented; they just stopped protecting themselves from their own understanding.
Verse 33 shifts the angle: even a person of knowledge acts according to their own nature, and Krishna asks whether forcing people against their grain actually works. The question of free will and conditioning enters. When ready, say: "3.33"
