Tathā dehāntara-prāptiḥ (BG 2.13). That is a fact. You believe or not believe, you are changing your body every moment. So simply you have no eyes to see, you have no brain to understand. You may be . . . because you are cat and dog, you cannot understand. Because the cats and dogs, they cannot understand that there is another life after this dog's body and cat's body. They cannot understand. So anyone who cannot understand the simply . . . simple truth of the transmigration of the soul, He's no better than this cat and dog.
So this karmīs are like that. Some of them understand. They at least believe in future life. But they do not know how to stop this trans . . . transmigration of the soul. That they do not know, karmīs. They know, "It is unavoidable to change the bodies. So there is no need of endeavouring . . ." Therefore they do not know, they cannot know, neither can they can do. They simply, "Yes, there is life, but let me become in more comfortable situation." Just like in this life they're trying just to become in comfortable situation of this body, similarly, when they understand that, accepting at least that there is next life, they want to go to the heavenly planet, svarga. But they do not know that that is also not ultimate happiness. That is stated in the Bhagavad-gītā. You read nicely.
