These deluded ones, getting into āsura wombs birth after birth, do not reach Me (the Supreme), and sink into still inferior states, O son of Kunti.
Courting āsura wombs one after another, these deluded ones struggle hard to realize their external, material, physical ambitions. But it is a vicious circle, with no real satisfaction or conclusion. Their life remains distracted, not focussed. Sensory enjoyments only weaken the senses. There is nothing elevating and ennobling in them. None of the āsuric people comes to think of the supreme Reality. Sensory glamour and pomp alone rule their thoughts.
For these people, instead of progressive evolution, their status sinks to the lowest. Earlier Krishna said about the proud advocates of Vedic rituals (2.42-44), who consider there is nothing superior. Having no discrimination to discern what Vedas truly reveal, they remain bogged down to the promised non-verifiable fruits of rituals. Attracted and deluded by enjoyment (bhoga), their intelligence does not become resolute. They too do not evolve, but their status is stagnant, cyclic.
In the case of Asuras, they are not able to recognize the harm in their approach. Moreover, given to evil tendencies, they are driven to still inferior births.
