In the Bhagavad-gītā it is plainly said, mūḍha. Mūḍha means asses, rascal. He does not know his own interest. He is called mūḍha, ass. Just like ass. Ass is whole day working with tons of cloth on his back, but he does not... Not a piece of cloth belongs to him. This is ass. And he is working so hard only for a morsel of grass, which is available everywhere. But he is thinking that "This gentleman, washerman, is giving me food." This is ass. Such food can be available anywhere and everywhere, but he is thinking like that and working so hard. So karmīs are like that.
