Bhagavān Kṛṣṇa continues explaining why he remains engaged in action even though he has nothing to gain. In the previous verse, he said that people follow his path in every way. Now he explains the consequence if he failed to act.

Utsīdeyuḥ ime lokāḥ means “these worlds would decline or perish.” Kṛṣṇa is not saying that he would directly destroy people with a weapon. The point is subtler. If the greatest model neglects duty, others will imitate that neglect. When respected people stop following dharma, ordinary people become confused and careless.

Then Bhagavān says, saṅkarasya ca kartā syām — I would become the cause of saṅkara. Here saṅkara means confusion and disorder in society, especially confusion regarding duties. People would no longer know what is to be done, who should do what, what values should guide life, and how to live in harmony. Varṇa and āśrama duties would become unclear or ignored.

This confusion does not always show its result immediately. A society may violate dharma for some time and still appear successful. But gradually the damage appears. When people exploit nature, neglect family duties, abandon worship, ignore elders, choose professions only by greed, misuse power, and live only for consumption, the order weakens. The results may appear as social disorder, disease, ecological damage, moral confusion, and spiritual decline.

Finally, upahanyām imāḥ prajāḥ means “I would destroy these people.” Again, this is not direct violence. It means that by failing to set the right example, Kṛṣṇa would indirectly become responsible for the decline of society. Therefore, for lokasaṅgraha, he acts carefully.

The lesson for Arjuna is direct. If Arjuna, a respected warrior, avoids his duty, others may imitate him and justify their own escape from responsibility. Therefore, he must act, not only for himself, but to preserve dharma and social order.
