"Mūḍha means rascal, ass. Because nobody knows what is the aim of life. They're exactly like the ass. He does not know what is his interest. Unnecessarily he is carrying three tons of cloth of the washerman. Therefore he is called ass. His gain is a little morsel of grass. He can get grass anywhere. Still, he is thinking, 'I am obliged to this washerman. Because he is supplying me grass, therefore I must have three tons of cloth on my back.' This is ass. This is ass. He has no interest. Not a single cloth belongs to him, and he is carrying, oh, three tons of cloth. Therefore the ass. Ass means one who does not know his interest, and he works unnecessarily and wastes his time.
So everyone in this material world, he does not know what is the aim of life. Unnecessarily he is making plan—this plan, that plan, this plan, that plan—and all plan is being frustrated by the laws of nature. Daivī hy eṣā guṇamayī mama māyā duratyayā (BG 7.14). Every plan will fail. And those who are plan-making persons, they are all rascals. They do not know that what kind of plan should be made. The plan should be made that everyone should be God conscious. Then every plan will be successful. Otherwise all, everything will fail."
