I am abundantly rich; I am well born. Who is there equal to me? I shall do sacrifices. I will give liberally. I will rejoice and revel – thus they thrive blinded by ignorance.
The difference in humans is not so much in their bodies, limbs and senses, but in their minds, their constitution. The same mind can produce varied thoughts, feelings, emotions and ambitions. These can be noble and lofty. They can as well be just the opposite. Here is the illustration of such ignoble and wicked thoughts, feelings and motivations.
Unless one cultivates the habit of discerning the intrinsic wrong in his thinking, and corrects it in time, the evil resolve will grow to terrible proportions. The disaster it works will be indescribable. Krishna is illustrating how gravely wrong and harmful the wicked thoughts can be.
The cruel mind gloats over its own ambitions and finds arguments to support them and boost its ego, infatuation and delusion. All the claims mentioned above are a result of this haughty self-aggrandizing nature.
